| Abstract(in English) | Expanding the capacity of satellite communication systems requires the use of onboard switching and regenerative relay techniques. However, there are obvious difficulties in applying new communication technology that has appeared since a launch if a new modem and baseband switch are required to be loaded on a satellite. Currently, the lifetime of a communications satellite in orbit is from 10 to 20 years, and it is impossible to exchange or upgrade mission equipment loaded on a satellite after its deployment in space. This paper describes reconfigurable communication equipment to be loaded on a small experimental satellite, "SmartSat-1". The reconfigurable communication equipment includes an onboard software radio system that consists of reconfigurable devices. New functions can be added by installing new configurations sent from a ground terminal after launching. The radiation testing results of S-RAM type FPGA are also described. |
