Abstract
Very long baseline interferometry (VLBI) is a technique in astronomy where several distant radio telescopes observe the same source and the received signals are recorded and later correlated to produce an image with a larger resolution. An e-VLBI experiment is a VLBI experiment where the data are transferred directly over the Internet and correlated in real time.
The primary task of JIVE is the correlation of data from the EVN telescopes [2] all around Europe. A special purpose-built hardware correlator is used for data processing. We are currently investigating the capabilities of a next-generation software correlator using Grid processing power. In this chapter we describe the design of this software correlator.
