Abstract

Following the success of the first VLBI Space Observatory Programme (VSOP), a satellite of a next space VLBI project, ASTRO-G/VSOP-2, is being designed. Very long baseline interferometry (VLBI) is a technique to achieve very high angular resolution imaging of celestial radio sources by combining the signals from widely separated radio telescopes. Space VLBI extends the separation beyond the Earth by placing one telescope on a satellite.
