This paper reports about CubeSat that is developing at SokuUniversity. Shooting the photos of earth and transmission of our song to ground station are the main mission. The operating frequency is in the amateur communication band. A UHF (f=430MHz) band will be used for the downlink, and a VHF (f=144MHz) will be used for the uplink. We've already developed TNC (Terminal Node Controller) for downlink at ARLISS2002. Feature of the Soka University Satellite is using FPGA (Field Programmable Gate Array) for control equipments. Advantages of using FPGA are design flexibility, small size, high speed processing and flight proven. You can have almost any logics in FPGA. Also you can have CPU in FPGA. There are reasons why we selected it for our CubeSat.
