| Abstract: |
We will introduce the observing system and operation of the ASTRO-G satellite which is the spacecraft for the VSOP-2 project that follows the success of the first space VLBI project, VSOP. VSOP-2 will have 10 times higher angular resolution (34 μasec) and 10 times higher frequency (43 GHz), compared with VSOP, in order to observe the innermost regions of AGN jets and astronomical masers. To achieve good performance, we must obtain the 10 times higher sensitivity using new technologies. The new technologies involve a large precision antenna, fast-position switching capability, a new MMIC Low Noise Amplifiers, and a 1 GHz wide-band down-link. We must obtain sufficient quantity of observation time with close collaboration among ASTRO-G, ground telescopes, and tracking stations. We are forming a new international council (VISC2) to provide mission guidance on all scientific aspects related to the VSOP-2 mission.. |
