A unique lag-based VLBI correlator system has been developed for the purpose of supporting both S2-based Space VLBI observations in the Japanese-led VSOP mission and the Canadian Geodetic VLBI program. The system architecture has been designed so that replication of a small number of modules can be used to construct systems with a wide range of sizes.(More)
This article summarizes the results of IVS Working Group 3 'VLBI2010', which was charged with creating a vision for a new geodetic VLBI instrument that will meet requirements for the coming decades. This comes at a time when problems with aging antennas, a deteriorating radio frequency environment due to interference, obsolete electronics, and high(More)
