eVLBI is the
process of using high speed networks to connect radio
telescopes separated by large distances (100-1000s of km) instead of
the traditional method of recording onto magnetic tape and shipping
the recorded data to a central correlator. The ATNF, in collaboration
with Curtin University, the University of
Tasmania, and Swinburne University of Technology have
upgraded the LBA for eVLBI usage.
