Autographa precationis. Autographa precationis (common looper moth) is a moth of the family Noctuidae. It is found in eastern and central North America.The wingspan is 30–38 mm. Adults are on wing from April to October depending on the location. There are three or more generations per year.The larvae feed on various forbs, including "Apiaceae", "Asteraceae", "Brassicaceae", "Chenopodiaceae", "Convolvulaceae", "Fabaceae", "Malvaceae", "Plantaginaceae" and "Verbenaceae" species.## Identification.The common looper is thought to have recently moved into the greater niche provided by more soybean planting in its range, with larvae observed in the wild feeding on soybean plants in addition to their usual fare. Notably,.

Autographa precationis. their digestibility and efficiency of food utilization for soybeans was not as high as with "Pseudoplusia includens," suggesting host plant preference for common loopers is slightly different. Visually, the two species are strikingly similar, so it is easy to confuse the two, but notably the silver spots on the wings of the Common Looper are usually conjoined, while the spots on the wings of "P. includens" are separated, and their wings are shinier than those of "A. precationis". Larvae of this species have 21-23 crochets per proleg, and are bright green, with a small black marks (false eyes) on each.

Megathura crenulata. Megathura crenulata is a northeastern Pacific Ocean species of limpet in the family Fissurellidae known commonly as the great keyhole limpet or giant keyhole limpet. "Megathura" is a monotypic genus; in other words, this is the only species in that genus. This species occurs along the rocky coast of western North America, its distribution extending from Southern California to the Baja California peninsula in Mexico. It is found in the intertidal zone and in the sea up to a depth of 33 meters.## Description.Limpets of this family have a hole at the top of the shell, the portal through which.

Megathura crenulata. waste products are released. This makes them different from the true limpets, which release waste from the mantle beneath the shell. This species is one of the largest keyhole limpets.## Biology.This species consumes a varied diet of plant, animal, protist, and algal material. It has been noted to consume filamentous cyanobacteria, diatoms, brown and red algaes such as seaweeds, seagrass, forams, hydrozoans, bryozoans, nematodes, bivalves, gastropods, crustaceans, and tunicates. The larger part of its diet is composed of brown and red algae, tunicates, hydrozoans of the genus "Eudendrium" and bryozoans of the genus "Crisia"."M. crenulata" has been used for experimental.

Unlike hemoglobin, the hemocyanin is not bound to cells but is simply dissolved in the hemolymph, the fluid part of the blood.## Keyhole limpet hemocyanin.Keyhole limpet hemocyanin from "Megathura crenulata" is used as vaccine carrier protein. Keyhole limpet hemocyanin (KLH) is a copper containing respiratory protein, similar to hemoglobin in humans. KLH is a large protein that acts as the hapten carrier part of the vaccine component, and is so far thought to be.

Megathura crenulata. non-toxic. The major potential use of KLH is for bladder carcinoma by stimulating a specific immune response, but there are many other medical uses such as stress assessment, understanding inflammatory conditions, and treating drug addiction. Vaccines and other KLH uses are in the research or trial phases. A liter of blood from a keyhole limpet will produce 20 grams of protein, which can be worth as much as $100,000.Beninger, P.

Cucurbita foetidissima. Cucurbita foetidissima is a tuberous xerophytic plant found in the central and southwestern United States and northern Mexico. It has numerous common names, including: buffalo gourd, calabazilla, chilicote, coyote gourd, fetid gourd, fetid wild pumpkin, Missouri gourd, prairie gourd, stinking gourd, wild gourd, and wild pumpkin. The type specimen was collected from Mexico by Alexander von Humboldt and Aimé Bonpland sometime before 1817. In Latin, foetidissima means ill smelling.The feral perennial buffalo gourd has evolved in the semiarid regions and is well-adapted to desert environments. It contains high amounts of protein and carbohydrates and yields abundant oil. The carbohydrates that.

Cucurbita foetidissima. are formed in the tap root have led to the idea of growing the plant for biofuel.The fruit is consumed by both humans and animals. When mature, a stage marked by increasing desiccation of vine, leaves, fruit-stem, and fruit, the fruit begins its final gourd stage.Geographic location and genetics make it highly likely that "Cucurbita scabridifolia" originated as a naturally occurring hybrid of "C. foetidissima" and "Cucurbita pedatifolia".## Morphology and cultivation."Cucurbita foetidissima" requires little water and grows best in semiarid and arid environments. Warm weather is required during the five- to eight-month vegetation period. This perennial is well adapted to.

Andropogon gerardi. Andropogon gerardi, commonly known as big bluestem, is a species of tall grass native to much of the Great Plains and grassland regions of central and eastern North America. It is also known as tall bluestem, bluejoint, and turkeyfoot.## Taxonomy."Andropogon gerardi" was formally named in 1792 by Fulgenzio Vitman. It was named for French botanist Louis Gérard, who had first described the plant from specimens that had been cultivated in Provence, France.Kew's International Plant Names Index and USDA Germplasm Resources Information Network reject the spelling "gerardii and provide reasoning for "gerardi as being the correct spelling for the specific epithet.

Andropogon gerardi. of this taxon. "Andropogon gerardii" still makes appearances in various literature, including other USDA publications.## Description.Big bluestem is a perennial warm-season bunchgrass. It is tolerant of a wide range of soil conditions. The main roots are 6 - 10 (ft) deep, and the plants send out strong, tough rhizomes, so it forms very strong sod. Depending on soil and moisture conditions, it grows to a height of 1 - 3 (m). The stem base turns blue or purple as it matures.Big bluestem blooms in the summer and seeds into the fall. The inflorescence (cluster of flowers) is a raceme of.

Andropogon gerardi. two to six, most commonly three, narrow spike-like racemes alternately arranged along the top of the stem. It somewhat resembles a wild turkey's foot. Each raceme contains pairs of spikelets. Each pair has a stalked spikelet with another stalkless spikelet at the base of the stalk. The stalkless spikelet usually has a fertile, perfect floret (with both female and male parts) and an awn (bristle), and the stalked spikelet is awnless, and is sterile or has a staminate (male) flower.## Ecology.Big bluestem is a midsuccessional grass in prairie and other grassland ecosystems. It grows in tall, dense stands that can.

Andropogon gerardi. outcompete other plant species. The stands grow until disturbance interrupts their spread. It is shade intolerant and is adapted to fire.It is a host to larvae of several species of butterflies, including the arogos skipper, byssus skipper, cobweb skipper, common wood nymph, Delaware skipper, and dusted skipper.The larvae of the leaf beetle "Diabrotica cristata" feed on the roots and the adults visit the flowers of other species of prairie flowers. Many ants decorate their nests with the seeds, including "Formica glacialis", "F. montana", and "F. subsericea". Several species of ants, such as "F. glacialis", "F. montana", "F. subsericea", "Lasius minutus",.

Andropogon gerardi. and "L. umbratus" build nests around the base of this bunchgrass, forming large soil mounds. In larger mounds, the nest is shared by multiple species of ants, and is "likened to an apartment complex with each ant species in its own nest partition". Up to 12 species of ants have been recorded in mounds found in the Chicago region.The rust fungus "Puccinia andropogonis" forms black telia on the leaves.## Uses.The grass and its variants are good forage for horses and cattle, and can also be cut and used for hay. The grass is high in protein. While not considered the.

Andropogon gerardi. highest quality native forage found in the United States, it has long been considered a desirable and ecologically important grass by cattle ranchers and rangeland ecologists.Big bluestem is cultivated by specialty plant nurseries for its drought tolerance and native status. It is often grown for wildlife gardens, natural landscaping, and grassland habitat restoration projects.Due to its high biomass, big bluestem is being considered as a potential feedstock for ethanol production.## Symbols."Andropogon gerardi" is the state grass of Illinois and Missouri and the official prairie grass of Manitoba.

Falun Mine. Falun Mine (Swedish: "Falu Gruva") was a mine in Falun, Sweden, that operated for a millennium from the 10th century to 1992. It produced as much as two-thirds of Europe's copper needs and helped fund many of Sweden's wars in the 17th century. Technological developments at the mine had a profound influence on mining globally for two centuries. The mine is now a museum and in 2001 was designated a UNESCO World Heritage Site.## History.There are no written accounts establishing exactly when mining operations at Falun Mine began. Archaeological and geological studies indicate, with considerable uncertainty, that mining operations started.

Falun Mine. sometime around the year 1000. No significant activities had begun before 850, but the mine was definitely operating by 1080. Objects from the 10th century have been found containing copper from the mine. In the beginning, operations were of a small scale, with local farmers gathering ore, smelting it, and using the metal for household needs.Around the time of Magnus III, king of Sweden from 1275 to 1290, a more professional operation began to take place. Nobles and foreign merchants from Lübeck had taken over from farmers. The merchants transported and sold the copper in Europe but also influenced the.

Falun Mine. operations and developed the methods and technology used for mining. The first written document about the mine is from 1288; it records that, in exchange for an estate, the Bishop of Västerås acquired a 12.5% interest in the mine.By the mid 14th century, the mine had grown into a vital national resource, and a large part of the revenues for the Swedish state in the coming centuries would be from the mine. The then king, Magnus IV, visited the area personally and drafted a charter for mining operations, ensuring the financial interest of the sovereign.## Methods.The principal method for extracting.

Falun Mine. copper was heating the rock via large fires, known as fire-setting. When the rock cooled down, it would become brittle and crack, allowing manual tools such as wedges and sledge hammers to be brought to bear. After the ore had been transported out of the mine it was roasted to reduce sulfur content in open hearths. The thick, poisonous smoke produced would be a distinguishing feature of the Falun area for centuries. After the roasting, the ore was smelted; the output of which was a copper rich material. The cycle of roasting and smelting was repeated several times until crude.

Falun Mine. copper was produced. This was the final output from the mine; further refinement took place at copper refineries elsewhere. This process was used without any major change for seven centuries, until the end of the 19th century. It is likely that the methods and technology for fire-setting and drainage were imported from German mines, such as in the Harz Mountains.## Free miners.The organizational structure of Falun Mine created under the 1347 charter was advanced for its time. Free miners owned shares of the operation, proportional to their ownership of copper smelters. The structure was precursor to modern joint stock companies,.

Falun Mine. and Stora Enso, the modern successor to the old mining company, is often referred to as the oldest joint stock company still operational in the world.## Golden era.In the 17th century, production capacity peaked. During this time, the output from the mine was used to fund various wars of Sweden during its great power era. The Privy Council of Sweden referred to the mine as the nation's treasury and stronghold. The point of maximum production occurred in 1650, with over 3,000 tonnes of copper produced.The mountain had been mined for nearly half a millennium towards the end of its golden.

Falun Mine. era. Production had intensified in the preceding decades, and by 1687 the rock was crisscrossed by numerous shafts and cave-ins were not unusual. Great effort went into producing maps of the mine for navigation, but there was no overall organization nor any estimation of the strength of the mountain. In the summer of 1687, great rumblings could be heard regularly from the mountain. On Midsummer's Eve of that year, the dividing wall between the main pits and the foundations gave way, and a significant portion of the mine collapsed. This could easily have become a great catastrophe, killing and trapping.

Falun Mine. the hundreds of men working in the mine, had it not occurred on Midsummer's Eve, one of the two days of the year on which the miners were not working, the other being Christmas.## Life in the mine.Fires were lit at the end of the day to heat the ore and allowed to burn through the night. The next morning the fires would be put out and the ore broken loose. In this manner, the miners could advance about 1 (m) per month. The miners working the fires and breaking the rock were the best paid and most skilled. Hand.

Falun Mine. barrows were used to transport the broken ore, in relays of about 20 (m) with multiple teams working long distances. This was usually the work newcomers were assigned to prove themselves. The work was hard and the mines very hot from the constant fires, and the miners were good customers of local drinking establishments. Drunkenness was considered quite normal for miners.Carl Linnaeus visited the mine and produced a vivid description of the life of the miners. He described that the miners climbed rickety ladders with sweat pouring from their bodies like "water from a bath". He continued: "The Falun Mine.

Falun Mine. is one of the great wonders of Sweden but as horrible as hell itself". Linnaeus' description of the environment the miners worked in is as follows: "Soot and darkness surrounded them on all sides. Stones, gravel, corrosive vitriol, drips, smoke, fumes, heat, dust, were everywhere".## Economic impact.Sweden had a virtual monopoly on copper which it retained throughout the 17th century. The only other country with a comparable copper output was Japan, but European imports from Japan were insignificant. In 1690, Erik Odhelius, a prominent metallurgist, was dispatched by the King to survey the European metal market. Although copper production had.

Falun Mine. already begun to decline by the time he made his report, something Odhelius made no secret of, he stated, "For the production of copper Sweden has always been like a mother, and although in many places within and without Europe some copper is extracted it counts for nothing next to the abundance of Swedish copper".By modern standards, however, the output was not large. Peak production barely reached 3,000 tonnes of copper per year, falling to less than 2,000 tonnes by 1665; from 1710 to 1720 it was barely 1,000 tonnes per year. Present worldwide copper production is 18.3 million tons.

Falun Mine. economically viable. On December 8, 1992, the last shot was fired in the mine, and all commercial mining ceased. Today the mine is owned by the Stora Kopparberget foundation which operates the museum and tours.## World Heritage Site.In 2001 Falun Mine was selected as a UNESCO World Heritage Site, one of 15 in Sweden. In addition to the mine itself, the World Heritage area covers the town of Falun, including 17th century miners’ cottages, residential areas, and Bergsmansbygden, a wider area that the free miners settled and in which they often built estates mirroring their wealth.## Museum.The museum has around.

Falun Mine. 100,000 visitors per year. It displays the history of mining at Falun Mine through the centuries; including the production of minerals, models of machinery, tools, and the people at the mine. It also has a large collection of portraits, starting from the 17th century, of significant people at the mine. Falugruva.se.

Parka. A parka or anorak is a type of coat with a hood, often lined with fur or faux fur. This kind of garment is a staple of Inuit clothing, traditionally made from caribou or seal skin, for hunting and kayaking in the frigid Arctic. Some Inuit anoraks require regular coating with fish oil to retain their water resistance.The words "anorak" and "parka" have been used interchangeably, but they are somewhat different garments. Strictly speaking, an anorak is a waterproof, hooded, pull-over jacket without a front opening, and sometimes drawstrings at the waist and cuffs, and a parka is a hip-length.

Parka. is sometimes used as a mildly derogatory term.The word "parka" is derived from the Nenets language. In the Aleutian Islands the word simply means "animal skin". It first entered the English written record in a 1625 work by Samuel Purchas.The Inuit who speak Inuktitut use parkas and have various terms related to them as follows:## N-3B ("scrub snorkel" or "snorkel") parka.The original snorkel parka (USAF N-3B parka, which is 3/4 length and has a full, attached hood; the similar N-2B parka is waist-length and has an attached split hood) was developed in the United States during the early 1950s for.

Unmanned aerial vehicle. An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention.UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous.

Unmanned aerial vehicle. for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include forest fire monitoring, aerial photography, product deliveries, agriculture, policing and surveillance, infrastructure inspections, entertainment, science, smuggling, and drone racing.## Terminology.Many terms are used for aircraft which fly without any persons on board:The term drone has been used from the early days of aviation, being applied to remotely-flown target aircraft used for practice firing of a battleship's guns, such as the 1920s Fairey Queen and 1930s de Havilland Queen Bee. Later.

Unmanned aerial vehicle. examples included the Airspeed Queen Wasp and Miles Queen Martinet, before ultimate replacement by the GAF Jindivik. The term remains in common use. In addition to the software, autonomous drones also employ a host of advanced technologies that allow them to carry out their missions without human intervention, such as cloud computing, computer vision, artificial intelligence, machine learning, deep learning, and thermal sensors. For recreational uses, an aerial photography drone (as opposed to a UAV) is an aircraft that has first-person video, autonomous capabilities, or both.An unmanned aerial vehicle (UAV) is defined as a "powered, aerial vehicle that does not.

Unmanned aerial vehicle. carry a human operator, uses aerodynamic forces to provide vehicle lift, can fly autonomously or be piloted remotely, can be expendable or recoverable, and can carry a lethal or nonlethal payload". UAV is a term that is commonly applied to military use cases. However missiles with warheads are not considered UAVs because the vehicle itself is a munition. Also, the relation of UAVs to remote controlled model aircraft is unclear, UAVs may or may not include remote-controlled model aircraft. Some jurisdictions base their definition on size or weight; however, the US FAA defines any uncrewed flying craft as a UAV.

Unmanned aerial vehicle. regardless of size. The term "unmanned aircraft system" (UAS) was adopted by the United States Department of Defense (DoD) and the United States Federal Aviation Administration (FAA) in 2005 according to their Unmanned Aircraft System Roadmap 2005–2030. The International Civil Aviation Organization (ICAO) and the British Civil Aviation Authority adopted this term, also used in the European Union's Single-European-Sky (SES) Air-Traffic-Management (ATM) Research (SESAR Joint Undertaking) roadmap for 2020. This term emphasizes the importance of elements other than the aircraft. It includes elements such as ground control stations, data links and other support equipment. A similar term is an "unmanned-aircraft.

Unmanned aerial vehicle. vehicle system" (UAVS), "remotely piloted aerial vehicle" (RPAV), "remotely piloted aircraft system" (RPAS). Many similar terms are in use. "Unoccupied" and "uninhabited" are occasionally used as alternatives to "unmanned". Under new regulations which came into effect 1 June 2019, the term RPAS (Remotely Piloted Aircraft System) has been adopted by the Canadian Government to mean "a set of configurable elements consisting of a remotely piloted aircraft, its control station, the command and control links and any other system elements required during flight operation".## Classification types.UAVs may be classified like any other aircraft, according to design configuration such as weight or.

Unmanned aerial vehicle. engine type, maximum flight altitude, degree of operational autonomy, operational role, etc. According to the United States Department of Defense, UAVs are classified into five categories below:Other classifications of UAVs include:## Range and endurance.There are usually five categories when UAVs are classified by range and endurance:## Size.There are usually four categories when UAVs are classified by size, with at least one of the dimensions (length or wingspan) meet the following respective limits:## Weight.Based on their weight, drones can be classified into five categories — nano (weighing up to 250 g), Micro air vehicles (MAV) (250 g – 2 kg), Miniature.

Unmanned aerial vehicle. UAV or small (SUAV) (2–25 kg), medium (25–150 kg), and large (over 150 kg).## Degree of autonomy.Drones could also be classified based on the degree of autonomy in their flight operations. ICAO classifies uncrewed aircraft as either remotely piloted aircraft or fully autonomous. Some UAVs offer intermediate degrees of autonomy. For example, a vehicle may be remotely piloted in most contexts but have an autonomous return-to-base operation. Some aircraft types may optionally fly manned or as UAVs, which may include manned aircraft transformed into uncrewed or Optionally Piloted UAVs (OPVs).## Altitude.Based on the altitude, the following UAV classifications have been.

Unmanned aerial vehicle. Carrier Guidance System (CACGS) for UAVs## Composite criteria.An example of classification based on the composite criteria is U.S. Military's unmanned aerial systems (UAS) classification of UAVs based on weight, maximum altitude and speed of the UAV component.## History.## Early drones.The earliest recorded use of an unmanned aerial vehicle for warfighting occurred in July 1849, with a balloon carrier (the precursor to the aircraft carrier) in the first offensive use of air power in naval aviation. Austrian forces besieging Venice attempted to launch some 200 incendiary balloons at the besieged city. The balloons were launched mainly from land; however, some were.

Unmanned aerial vehicle. also launched from the Austrian ship . At least one bomb fell in the city; however, due to the wind changing after launch, most of the balloons missed their target, and some drifted back over Austrian lines and the launching ship "Vulcano".The Spanish engineer Leonardo Torres y Quevedo introduced a radio-based control-system called the "Telekino" at the Paris Academy of Science in 1903 with the intention of testing an airship of his own design without risking human lives.Significant development of drones started in the 1900s, and originally focused on providing practice targets for training military personnel. The earliest attempt at.

Unmanned aerial vehicle. a powered UAV was A. M. Low's "Aerial Target" in 1916. Low confirmed that Geoffrey de Havilland's monoplane was the one that flew under control on 21 March 1917 using his radio system. Following this successful demonstration in the spring of 1917 Low was transferred to develop aircraft controlled fast motor launches D.C.B.s with the Royal Navy in 1918 intended to attack shipping and port installations and he also assisted Wing Commander Brock in preparations for the Zeebrugge Raid. Other British unmanned developments followed, leading to the fleet of over 400 de Havilland 82 Queen Bee aerial targets that went.

Unmanned aerial vehicle. in the late 1930s.## World War II.In 1940 Denny started the Radioplane Company and more models emerged during World War II used both to train antiaircraft gunners and to fly attack-missions. Nazi Germany produced and used various UAV aircraft during the war, like the Argus As 292 and the V-1 flying bomb with a jet engine.## Postwar period.After World War II development continued in vehicles such as the American JB-4 (using television/radio-command guidance), the Australian GAF Jindivik and Teledyne Ryan Firebee I of 1951, while companies like Beechcraft offered their Model 1001 for the U.S. Navy in 1955. Nevertheless, they.

Unmanned aerial vehicle. were little more than remote-controlled airplanes until the Vietnam War.In 1959 the U.S. Air Force, concerned about losing pilots over hostile territory, began planning for the use of uncrewed aircraft. Planning intensified after the Soviet Union shot down a U-2 in 1960. Within days, a highly-classified UAV program started under the code name of "Red Wagon". The August 1964 clash in the Tonkin Gulf between naval units of the U.S. and the North Vietnamese Navy initiated America's highly-classified UAVs (Ryan Model 147, Ryan AQM-91 Firefly, Lockheed D-21) into their first combat missions of the Vietnam War. When the Chinese government.

Unmanned aerial vehicle. showed photographs of downed U.S. UAVs via "Wide World Photos", the official U.S. response was "no comment".During the War of Attrition (1967–1970) in the Middle East, Israeli intelligence tested the first tactical UAVs installed with reconnaissance cameras, which successfully returned photos from across the Suez Canal. This was the first time that tactical UAVs that could be launched and landed on any short runway (unlike the heavier jet-based UAVs) were developed and tested in battle.In the 1973 Yom Kippur War, Israel used UAVs as decoys to spur opposing forces into wasting expensive anti-aircraft missiles. After the 1973 Yom Kippur war,.

Unmanned aerial vehicle. a few key people from the team that developed this early UAV joined a small startup company that aimed to develop UAVs into a commercial product, eventually purchased by Tadiran and leading to the development of the first Israeli UAV.In 1973 the U.S. military officially confirmed that they had been using UAVs in Southeast Asia (Vietnam). Over 5,000 U.S. airmen had been killed and over 1,000 more were missing or captured. The USAF 100th Strategic Reconnaissance Wing flew about 3,435 UAV missions during the war at a cost of about 554 UAVs lost to all causes. In the words of.

Unmanned aerial vehicle. USAF General George S. Brown, Commander, Air Force Systems Command, in 1972, "The only reason we need (UAVs) is that we don't want to needlessly expend the man in the cockpit." Later that year, General John C. Meyer, Commander in Chief, Strategic Air Command, stated, "we let the drone do the high-risk flying ... the loss rate is high, but we are willing to risk more of them ...they save lives!"During the 1973 Yom Kippur War, Soviet-supplied surface-to-air missile-batteries in Egypt and Syria caused heavy damage to Israeli fighter jets. As a result, Israel developed the IAI Scout as the.

Unmanned aerial vehicle. first UAV with real-time surveillance. The images and radar decoys provided by these UAVs helped Israel to completely neutralize the Syrian air defenses at the start of the 1982 Lebanon War, resulting in no pilots downed. In Israel in 1987, UAVs were first used as proof-of-concept of super-agility, post-stall controlled flight in combat-flight simulations that involved tailless, stealth-technology-based, three-dimensional thrust vectoring flight-control, and jet-steering.## Modern UAVs.With the maturing and miniaturization of applicable technologies in the 1980s and 1990s, interest in UAVs grew within the higher echelons of the U.S. military. In the 1990s, the U.S. DoD gave a contract to.

Unmanned aerial vehicle. AAI Corporation along with Israeli company Malat. The U.S. Navy bought the AAI Pioneer UAV that AAI and Malat developed jointly. Many of these UAVs saw service in the 1991 Gulf War. UAVs demonstrated the possibility of cheaper, more capable fighting-machines, deployable without risk to aircrews. Initial generations primarily involved surveillance aircraft, but some carried armaments, such as the General Atomics MQ-1 Predator, that launched AGM-114 Hellfire air-to-ground missiles.CAPECON, a European Union project to develop UAVs, ran from 1 May 2002 to 31 December 2005. the United States Air Force (USAF) employed 7,494 UAVs almost one in three USAF aircraft.

Unmanned aerial vehicle. The Central Intelligence Agency also operated UAVs. By 2013 at least 50 countries used UAVs. China, Iran, Israel, Pakistan, Turkey, and others designed and built their own varieties. The use of drones has continued to increase. Due to their wide proliferation, no comprehensive list of UAV systems exists.The development of smart technologies and improved electrical-power systems led to a parallel increase in the use of drones for consumer and general aviation activities. As of 2021, quadcopter drones exemplify the widespread popularity of hobby radio-controlled aircraft and toys, however the use of UAVs in commercial and general aviation is limited by.

Unmanned aerial vehicle. a lack of autonomy and by new regulatory environments which require line-of-sight contact with the pilot.In 2020 a Kargu 2 drone hunted down and attacked a human target in Libya, according to a report from the UN Security Council's Panel of Experts on Libya, published in March 2021. This may have been the first time an autonomous killer-robot armed with lethal weaponry attacked human beings.Superior drone technology played a role in Azerbaijan's successes in the 2020 Nagorno-Karabakh war against Armenia.UAVs are also used in NASA missions. The Dragonfly spacecraft is being developed, and is aiming to reach and examine Saturn's.

Unmanned aerial vehicle. moon Titan. Its primary goal is to roam around the surface, expanding the amount of area to be researched previously seen by Landers. As a UAV, Dragonfly allows examination of potentially diverse types of soil. The drone is set to launch in 2027, and is estimated to take a seven more years to reach the Saturnian system.## Design.Crewed and uncrewed aircraft of the same type generally have recognizably similar physical components. The main exceptions are the cockpit and environmental control system or life support systems. Some UAVs carry payloads (such as a camera) that weigh considerably less than an adult.

Unmanned aerial vehicle. human, and as a result, can be considerably smaller. Though they carry heavy payloads, weaponized military UAVs are lighter than their crewed counterparts with comparable armaments.Small civilian UAVs have no life-critical systems, and can thus be built out of lighter but less sturdy materials and shapes, and can use less robustly tested electronic control systems. For small UAVs, the quadcopter design has become popular, though this layout is rarely used for crewed aircraft. Miniaturization means that less-powerful propulsion technologies can be used that are not feasible for crewed aircraft, such as small electric motors and batteries.Control systems for UAVs are.

Unmanned aerial vehicle. often different than crewed craft. For remote human control, a camera and video link almost always replace the cockpit windows; radio-transmitted digital commands replace physical cockpit controls. Autopilot software is used on both crewed and uncrewed aircraft, with varying feature sets.## Aircraft configuration.The primary difference from manned aeroplanes is the lack of need for a cockpit area and its windows. However some types are adapted from piloted examples, or are designed for optional piloted or unmanned operational modes. Air safety is also less of a critical requirement for unmanned aircraft, allowing the designer greater freedom to experiment. These two factors.

Unmanned aerial vehicle. have led to a great variety of airframe and engine configurations in UAVs.For conventional flight the flying wing and blended wing body offer light weight combined with low drag and stealth, and are popular configurations. Larger types which carry a variable payload are more likely to feature a distinct fuselage with a tail for stability, control and trim, although the wing configurations in use vary widely.For vertical flight, the tailless quadcopter requires a relatively simple control system and is common for smaller UAVs. However the mechanism does not scale well to larger aircraft, which tend to use a conventional single.

Unmanned aerial vehicle. rotor with collective and cyclic pitch control, along with a stabilising tail rotor.## Propulsion.Traditional internal combustion and jet engines remain in use for drones requiring long range. However for shorter-range missions electric power has almost entirely taken over. The distance record for a UAV (built from balsa wood and mylar skin) across the North Atlantic Ocean is held by a gasoline model airplane or UAV. Manard Hill "in 2003 when one of his creations flew 1,882 miles across the Atlantic Ocean on less than a gallon of fuel" holds this record.Besides the traditional piston engine, the Wankel rotary engine is.

Unmanned aerial vehicle. used by some drones. This type offers high power output for lower weight, with quieter and more vibration-free running. Claims have also been made for improved reliability and greater range.Small drones mostly use lithium-polymer batteries (Li-Po), while some larger vehicles have adopted the a hydrogen fuel cell. The energy density of modern Li-Po batteries is far less than gasoline or hydrogen. However electric motors are cheaper, lighter and quieter. Complex multi-engine, multi-propeller installations are under development with the goal of improving aerodynamic and propulsive efficiency. For such complex power installations, Battery elimination circuitry (BEC) may be used to centralize power.

Unmanned aerial vehicle. distribution and minimize heating, under the control of a microcontroller unit (MCU).## Ornithopters – wing propulsion.Flapping-wing ornithopters, imitating birds or insects, have been flown as microUAVs. Their inherent stealth recommends them for spy missions.Sub-1g microUAVs inspired by flies, albeit using a power tether, have been able to "land" on vertical surfaces. Other projects mimic the flight of beetles and other insects.## Computer control systems.UAV computing capability followed the advances of computing technology, beginning with analog controls and evolving into microcontrollers, then system-on-a-chip (SOC) and single-board computers (SBC).System hardware for small UAVs is often called the flight controller (FC), flight controller.

Unmanned aerial vehicle. board (FCB) or autopilot.## Architecture.## Sensors.Position and movement sensors give information about the aircraft state. Exteroceptive sensors deal with external information like distance measurements, while exproprioceptive ones correlate internal and external states.Non-cooperative sensors are able to detect targets autonomously so they are used for separation assurance and collision avoidance.Degrees of freedom (DOF) refers to both the amount and quality of sensors on board: 6 DOF implies 3-axis gyroscopes and accelerometers (a typical inertial measurement unit IMU), 9 DOF refers to an IMU plus a compass, 10 DOF adds a barometer and 11 DOF usually adds a GPS receiver.## Actuators.UAV actuators.

Unmanned aerial vehicle. include digital electronic speed controllers (which control the RPM of the motors) linked to motors/engines and propellers, servomotors (for planes and helicopters mostly), weapons, payload actuators, LEDs and speakers.## Software.UAV software called the flight stack or autopilot. The purpose of the flight stack is to obtain data from sensors, control motors to ensure UAV stability, and facilitate ground control and mission planning communication.UAVs are real-time systems that require rapid response to changing sensor data. As a result, UAVs rely on single-board computers for their computational needs. Examples of such single-board computers include Raspberry Pis, Beagleboards, etc. shielded with NavIO, PXFMini,.

Unmanned aerial vehicle. etc. or designed from scratch such as NuttX, preemptive-RT Linux, Xenomai, Orocos-Robot Operating System or DDS-ROS 2.0.Civil-use open-source stacks include: Agilicious (also open-source hardware) ArduCopter CrazyFlie KKMultiCopter MultiWii BaseFlight (forked from MultiWii) CleanFlight (forked from BaseFlight) BetaFlight (forked from CleanFlight) iNav (forked from CleanFlight) RaceFlight (forked from CleanFlight) OpenPilot dRonin (forked from OpenPilot) LibrePilot (forked from OpenPilot) TauLabs (forked from OpenPilot) Paparazzi PX4 autopilot DroneCode (Umbrella organization managing PX4 within the Linux Foundation)Due to the open-source nature of UAV software, they can be customized to fit specific applications. For example, researchers from the Technical University of Košice have replaced the.

Unmanned aerial vehicle. default control algorithm of the PX4 autopilot. This flexibility and collaborative effort has led to a large number of different open-source stacks, some of which are forked from others, such as CleanFlight, which is forked from BaseFlight and from which three other stacks are forked from.## Loop principles.UAVs employ open-loop, closed-loop or hybrid control architectures. Open loop This type provides a positive control signal (faster, slower, left, right, up, down) without incorporating feedback from sensor data. Closed loop This type incorporates sensor feedback to adjust behavior (reduce speed to reflect tailwind, move to altitude 300 feet). The PID controller is.

Unmanned aerial vehicle. common. Sometimes, feedforward is employed, transferring the need to close the loop further.## Communications.UAVs use a radio for control and exchange of video and other data. Early UAVs had only narrowband uplink. Downlinks came later. These bi-directional narrowband radio links carried command and control (C&C) and telemetry data about the status of aircraft systems to the remote operator.In most modern UAV applications, video transmission is required. So instead of having separate links for C&C, telemetry and video traffic, a broadband link is used to carry all types of data. These broadband links can leverage quality of service techniques and carry.

Unmanned aerial vehicle. TCP/IP traffic that can be routed over the Internet.The radio signal from the operator side can be issued from either: Ground control – a human operating a radio transmitter/receiver, a smartphone, a tablet, a computer, or the original meaning of a military ground control station (GCS). Remote network system, such as satellite duplex data links for some military powers. Downstream digital video over mobile networks has also entered consumer markets, while direct UAV control uplink over the cellular mesh and LTE have been demonstrated and are in trials. Another aircraft, serving as a relay or mobile control station military manned-unmanned.

Unmanned aerial vehicle. teaming (MUM-T).Modern networking standards have explicitly considered drones and therefore include optimizations. The 5G standard has mandated reduced user plane latency to 1ms while using ultra-reliable and low-latency communications.## Autonomy.The level of autonomy in UAVs varies widely. UAV manufacturers often build in specific autonomous operations, such as: Self-level: attitude stabilization on the pitch and roll axes. Altitude hold: The aircraft maintains its altitude using barometric pressure and/or GPS data. Hover/position hold: Keep level pitch and roll, stable yaw heading and altitude while maintaining position using GNSS or inertial sensors. Headless mode: Pitch control relative to the position of the pilot.

Unmanned aerial vehicle. Performance considerations.## Flight envelope.UAVs can be programmed to perform aggressive maneuvers or landing/perching on inclined surfaces, and then to climb toward better communication spots. Some UAVs can control flight with varying flight modelisation, such as VTOL designs.UAVs can also implement perching on a flat vertical surface.## Endurance.UAV endurance is not constrained by the physiological capabilities of a human pilot.Because of their small size, low weight, low vibration and high power to weight ratio, Wankel rotary engines are used in many large UAVs. Their engine rotors cannot seize; the engine is not susceptible to shock-cooling during descent and it does not.

Unmanned aerial vehicle. require an enriched fuel mixture for cooling at high power. These attributes reduce fuel usage, increasing range or payload.Proper drone cooling is essential for long-term drone endurance. Overheating and subsequent engine failure is the most common cause of drone failure.Hydrogen fuel cells, using hydrogen power, may be able to extend the endurance of small UAVs, up to several hours.Micro air vehicles endurance is so far best achieved with flapping-wing UAVs, followed by planes and multirotors standing last, due to lower Reynolds number.Solar-electric UAVs, a concept originally championed by the AstroFlight Sunrise in 1974, have achieved flight times of several weeks.Solar-powered.

Unmanned aerial vehicle. atmospheric satellites ("atmosats") designed for operating at altitudes exceeding 20 km (12 miles, or 60,000 feet) for as long as five years could potentially perform duties more economically and with more versatility than low Earth orbit satellites. Likely applications include weather monitoring, disaster recovery, Earth imaging and communications.Electric UAVs powered by microwave power transmission or laser power beaming are other potential endurance solutions.Another application for a high endurance UAV would be to "stare" at a battlefield for a long interval (ARGUS-IS, Gorgon Stare, Integrated Sensor Is Structure) to record events that could then be played backwards to track battlefield activities.##.

Unmanned aerial vehicle. Reliability.Reliability improvements target all aspects of UAV systems, using resilience engineering and fault tolerance techniques.Individual reliability covers robustness of flight controllers, to ensure safety without excessive redundancy to minimize cost and weight. Besides, dynamic assessment of flight envelope allows damage-resilient UAVs, using non-linear analysis with ad hoc designed loops or neural networks. UAV software liability is bending toward the design and certifications of crewed avionics software.Swarm resilience involves maintaining operational capabilities and reconfiguring tasks given unit failures.## Applications.In recent years, autonomous drones have begun to transform various application areas as they can fly beyond visual line of sight (BVLOS) while.

Unmanned aerial vehicle. maximizing production, reducing costs and risks, ensuring site safety, security and regulatory compliance, and protecting the human workforce in times of a pandemic. They can also be used for consumer-related missions like package delivery, as demonstrated by Amazon Prime Air, and critical deliveries of health supplies.There are numerous civilian, commercial, military, and aerospace applications for UAVs. These include:General: Recreation, Disaster relief, archeology, conservation of biodiversity and habitat, law enforcement, crime, and terrorism. Commercial: Aerial surveillance, filmmaking, journalism, scientific research, surveying, cargo transport, mining, manufacturing, Forestry, solar farming, thermal energy, ports and agriculture.## Warfare.With extensive cost reductions and advancements in the.

Unmanned aerial vehicle. UAVs technology, the defense forces around the globe are increasingly using these for various applications such as surveillance, logistics, communication, attack and combat.As of 2020, seventeen countries have armed UAVs, and more than 100 countries use UAVs in a military capacity. The global military UAV market is dominated by companies based in the United States, Turkey, China, Israel and Iran. By sale numbers, the US held over 60% military-market share in 2017. Top military UAV manufactures are including General Atomics, Lockheed Martin, Northrop Grumman, Boeing, Baykar, TAI, IAIO, CASC and CAIG. China has established and expanded its presence in military.

Unmanned aerial vehicle. UAV market since 2010. Turkey also established and expanded its presence in military UAV market.Of the 18 countries that are known to have received military drones between 2010 to 2019, the top 12 all purchased their drones from China. According to a report of 2015, Israeli companies mainly focus on small surveillance UAV systems and by quantity of drones, Israel exported 60.7% (2014) of UAV on the market while the United States export 23.9% (2014). Between 2010 and 2014, there were 439 drones exchanged compared to 322 in the five years previous to that, among these only small fraction of.

Unmanned aerial vehicle. overall trade – just 11 (2.5%) of the 439 are armed drones. The US alone operated over 9,000 military UAVs in 2014; among them more than 7000 are RQ-11 Raven miniature UAVs. General Atomics is the dominant manufacturer with the Global Hawk and Predator/Mariner systems product-line.For intelligence and reconnaissance missions, the inherent stealth of micro UAV flapping-wing ornithopters, imitating birds or insects, offers potential for covert surveillance and makes them difficult targets to bring down.UAVs are used for reconnaissance, attack, demining, and target practice.## Civil.The civilian (commercial and general) drone market is dominated by Chinese companies. Chinese drone manufacturer DJI.

Unmanned aerial vehicle. alone had 74% of the civil market share in 2018, with no other company accounting for more than 5%, and with $11 billion forecast global sales in 2020. Following increased scrutiny of its activities, the US Interior Department grounded its fleet of DJI drones in 2020, while the Justice Department prohibited the use of federal funds for the purchase of DJI and other foreign made UAVs. DJI is followed by Chinese company Yuneec, US company 3D Robotics and French company Parrot with a significant gap in market share. As of May 2021, 873,576 UAVs have been registered with the US.

Unmanned aerial vehicle. FAA, of which 42% are categorized as commercial drones and 58% as recreational drones. 2018 NPD point to consumers increasingly purchasing drones with more advanced features with 33 percent growth in both the $500+ and $1000+ market segments.The civil UAV market is relatively new compared to the military one. Companies are emerging in both developed and developing nations at the same time. Many early stage startups have received support and funding from investors as is the case in the United States and by government agencies as is the case in India. Some universities offer research and training programs or degrees.

Unmanned aerial vehicle. Private entities also provide online and in-person training programs for both recreational and commercial UAV use.Consumer drones are also widely used by military organizations worldwide because of the cost-effective nature of consumer product. In 2018, Israeli military started to use DJI Mavic and Matrice series of UAV for light reconnaissance mission since the civil drones are easier to use and have higher reliability. DJI drones is also the most widely used commercial unmanned aerial system that the US Army has employed. DJI surveillance drones have also been used by Chinese police in Xinjiang since 2017.The global UAV market will reach.

Unmanned aerial vehicle. US$21.47 billion, with the Indian market touching the US$885.7 million mark, by 2021.Lighted drones are beginning to be used in nighttime displays for artistic and advertising purposes.## Aerial photography.Drones are ideally suited to capturing aerial shots in photography and cinematography, and are widely used for this purpose. Small drones avoid the need for precise coordination between pilot and cameraman, with the same person taking on both roles. However, big drones with professional cine cameras, there is usually a drone pilot and a camera operator who controls camera angle and lens. For example, the AERIGON cinema drone which is used in.

Unmanned aerial vehicle. film production in big blockbuster movies is operated by 2 people. Drones provide access to dangerous, remote or otherwise inaccessible sites.## Agriculture and forestry.As global demand for food production grows exponentially, resources are depleted, farmland is reduced, and agricultural labor is increasingly in short supply, there is an urgent need for more convenient and smarter agricultural solutions than traditional methods, and the agricultural drone and robotics industry is expected to make progress. Agricultural drones have been used in areas such as Africa to help build sustainable agriculture.The use of UAVs is also being investigated to help detect and fight wildfires,.

Unmanned aerial vehicle. whether through observation or launching pyrotechnic devices to start backfires.## Law enforcement.Police can use drones for applications such as search and rescue and traffic monitoring.## Safety and security.## Threats.## Nuisance.UAVs can threaten airspace security in numerous ways, including unintentional collisions or other interference with other aircraft, deliberate attacks or by distracting pilots or flight controllers. The first incident of a drone-airplane collision occurred in mid-October 2017 in Quebec City, Canada. The first recorded instance of a drone collision with a hot air balloon occurred on 10 August 2018 in Driggs, Idaho, United States; although there was no significant damage to.

Unmanned aerial vehicle. the balloon nor any injuries to its 3 occupants, the balloon pilot reported the incident to the National Transportation Safety Board, stating that "I hope this incident helps create a conversation of respect for nature, the airspace, and rules and regulations". Unauthorized UAV flights into or near major airports have prompted extended shutdowns of commercial flights.Drones caused significant disruption at Gatwick Airport during December 2018, needing the deployment of the British Army.In the United States, flying close to a wildfire is punishable by a maximum $25,000 fine. Nonetheless, in 2014 and 2015, firefighting air support in California was hindered on.

Unmanned aerial vehicle. several occasions, including at the Lake Fire and the North Fire. In response, California legislators introduced a bill that would allow firefighters to disable UAVs which invaded restricted airspace. The FAA later required registration of most UAVs.## Security vulnerabilities.By 2017, drones were being used to drop contraband into prisons.The interest in UAVs cyber security has been raised greatly after the Predator UAV video stream hijacking incident in 2009, where Islamic militants used cheap, off-the-shelf equipment to stream video feeds from a UAV. Another risk is the possibility of hijacking or jamming a UAV in flight. Several security researchers have made.

Unmanned aerial vehicle. public some vulnerabilities in commercial UAVs, in some cases even providing full source code or tools to reproduce their attacks. At a workshop on UAVs and privacy in October 2016, researchers from the Federal Trade Commission showed they were able to hack into three different consumer quadcopters and noted that UAV manufacturers can make their UAVs more secure by the basic security measures of encrypting the Wi-Fi signal and adding password protection.## Aggression.UAVs could be loaded with dangerous payloads, and crashed into vulnerable targets. Payloads could include explosives, chemical, radiological or biological hazards. UAVs with generally non-lethal payloads could possibly.

Unmanned aerial vehicle. be hacked and put to malicious purposes. Anti-UAV systems are being developed by states to counter this threat. This is, however, proving difficult. As Dr J. Rogers stated in an interview to A&T "There is a big debate out there at the moment about what the best way is to counter these small UAVs, whether they are used by hobbyists causing a bit of a nuisance or in a more sinister manner by a terrorist actor".## Countermeasures.## Counter unmanned air system.The malicious use of UAVs has led to the development of counter unmanned air system (C-UAS) technologies. Automatic tracking and.

Unmanned aerial vehicle. detection of UAVs from commercial cameras have become accurate thanks to the development of deep learning based machine learning algorithms. It is also possible to automatically identify UAVs across different cameras with different view points and hardware specification with re-identification methods. Commercial solutions such as the Aaronia AARTOS have been installed on major international airports. Anti-aircraft missile systems such as the Iron Dome are also being enhanced with C-UAS technologies. Utilising a smart UAV swarm to counter one or more hostile UAVs is also proposed.## Regulation.Regulatory bodies around the world are developing unmanned aircraft system traffic management solutions to better.

Unmanned aerial vehicle. integrate UAVs into airspace.The use of unmanned aerial vehicles is becoming increasingly regulated by the civil aviation authorities of individual countries. Regulatory regimes can differ significantly according to drone size and use. The International Civil Aviation Organization (ICAO) began exploring the use of drone technology as far back as 2005, which resulted in a 2011 report. France was among the first countries to set a national framework based on this report and larger aviation bodies such as the FAA and the EASA quickly followed suit. In 2021, the FAA published a rule requiring all commercially-used UAVs and all UAVs regardless.

Unmanned aerial vehicle. of intent weighing 250g or more to participate in Remote ID, which makes drone locations, controller locations, and other information public from takeoff to shutdown; this rule has since been challenged in the pending federal lawsuit "RaceDayQuads v.

De Havilland. The de Havilland Aircraft Company Limited () was a British aviation manufacturer established in late 1920 by Geoffrey de Havilland at Stag Lane Aerodrome Edgware on the outskirts of north London. Operations were later moved to Hatfield in Hertfordshire.Known for its innovation, de Havilland was responsible for a number of important aircraft, including the Moth biplane which revolutionised aviation in the 1920s; the 1930s Fox Moth, a commercial light passenger aircraft; the wooden World War II Mosquito multirole aircraft; and the pioneering passenger jet airliner Comet.The de Havilland company became a member of the Hawker Siddeley group in 1960, but.

De Havilland. lost its separate identity in 1963. Later, Hawker Siddeley merged into what is eventually known today as BAE Systems, the British aerospace and defence business. The de Havilland name lives on in De Havilland Canada, which owns the rights to the name and the aircraft produced by de Havilland's former Canadian subsidiary, including the Dash 8 regional airliner previously produced by Bombardier Aerospace.## History.## Origins.In January 1920 Geoffrey de Havilland was working for Airco as technical director and chief designer. BSA bought Airco on 20 January 1920 from George Holt Thomas on the say-so of one BSA director, Percy Martin,.

De Havilland. stronger. As a result, the Comet was extensively redesigned, with oval windows, structural reinforcements and other changes. Rival manufacturers meanwhile heeded the lessons learned from the Comet while developing their own aircraft. The Comet 4 enabled the de Havilland airliner to return to the skies in 1958. By then the United States had its Boeing 707 jet and the Douglas DC-8, both of which were faster and more economical to operate. Orders for the Comet dried up.Hawker Siddeley bought de Havilland in 1960 but kept it as a separate company until 1963. In that year it became the de Havilland.

De Havilland. Division of Hawker Siddeley Aviation and all types in production or development changed their designations from "DH" to "HS". De Havilland's final designs became the Hawker Siddeley Trident (originally the DH.121) and the innovative Hawker Siddley HS.125, originally the DH.125.The DH.121 design was modified to be smaller to fit the needs of one airline—British European Airways. Other airlines found it unattractive and turned to a rival tri-jet, the Boeing 727 which was much the same size as the initial DH.121 design. De Havilland, as Hawker Siddley, built only 117 Tridents, while Boeing went on to sell over 1,800 727s.De Havilland.

De Havilland. was established in March 1939, and work commenced on New Zealand's first aircraft factory at Rongotai. After World War II, the company undertook maintenance and refurbishment work until taken over by Hawker Siddeley International NZ Ltd in 1964. The site of the factory is now part of Wellington International Airport.## de Havilland Engines.As well as a prolific aircraft builder, de Havilland was also a significant producer of aero engines. This went against usual practice: usually engines are designed and produced by a dedicated company though in the UK the Bristol Aeroplane Company had a substantial engine business and Armstrong Whitworth.

De Havilland. Hertfordshire County Council for educational use: the site was then developed as Hatfield Technical College, which is now the College Lane Campus of the University of Hertfordshire. De Havilland was purchased by Hawker Siddeley in 1960 and merged into British Aerospace in 1978. The BAE site then closed in 1993, and the University of Hertfordshire purchased part of the site for the de Havilland Campus. Hatfield's aerospace history is recorded today in the names of local streets, such as Comet Way and Dragon Road.In September 2003 part of the former British aerospace site became the de Havilland campus of the.

La Recoleta Cemetery. () and a church, Our Lady of Pilar ("), built in 1732.The order was disbanded in 1822, and the garden of the convent was converted into the first public cemetery in Buenos Aires. Inaugurated on 17 November of the same year under the name of " (Northern Cemetery), those responsible for its creation were the then-Governor Martin Rodríguez, who would be eventually buried in the cemetery, and government minister Bernardino Rivadavia.The 1822 layout was done by French civil engineer Próspero Catelin, who also designed the current facade of the Buenos Aires Metropolitan Cathedral. The cemetery was last remodeled in 1881,.
