Spacecraft Design of VSOP-2
  As presented by Hirabayashi et al. (2004) these proceedings, the VSOP-2 mission is currently being planned. Various kinds of developments are being made for the misson, and here we introduce the large antenna, fast switching scheme using CMG, low noise receivers, gigabit data transmission, and high data rate sampling on-board. We are also studying the system configuration of the VSOP-2 satellite and the orbit appropriate for the expected launch vehicle, the M-V rocket. VSOP-2 science goals include imaging the accretion disks around the massive blackholes in the nuclei of the active galaxies, studies of magnetic field orientation and evolution in jets, and the highest resolution studies of spectral line masers and mega-masers. Here we describe the design and the development of the space antenna, high speed sampler, and the satellite system.
