European VLBI is undergoing a rapid development. On one hand
electronic or e-VLBI is changing the very nature of the European VLBI
Network (EVN), on the other hand a dramatically increased time
resolution will enable the EVN to image vast areas of sky at
unprecedented resolution. The resulting increase of data volumes will
require new calibration tools and new ways of computing, storing and
distributing data products.
Technological advances are changing the nature of VLBI. Disk based recording has already led to sustantial increases in sensitivity and with the advent of new telescopes and data acquisition systems VLBI will start penetrating the micro-Jansky sky. With the employment of fibre based communication networks as the basis for production, real-time VLBI networks will become a reality. This changes the way VLBI is done and removes bottlenecks in operation and scientific exploration. At the output side, fantastic new correlator output data rates and the ability to deal with these via powerful PC clusters promises to expand the typical VLBI field-of-view to scales previously reserved for connected, short baseline interferometers. These developments require new algorithms for user processing, as well as new interfaces to present the product to the users.
