超小型人工衛星HIT-SATのデータ処理系の開発  [in Japanese] Development of data handling unit for Pico-Satellite "HIT-SAT"  [in Japanese]

"Hokkaido satellite" is a 50kg small satellite, and the main mission is a remote sensing. The HIT-SAT had been developed by Hokkaido in order to demonstrate the performance of the attitude control system for "Hokkaido Satellite". The HIT-SAT is size 12cm cubed and weight 2.7kg. Attitude Control is an object of keeping satellite attitude by spin stabilization. The HIT-SAT was launched successfully on September, 23, 2006(JST) as a sub-payload of the M-V-7 Rocket. In this paper, we described a design of data handling unit for the HIT-SAT and the result in orbit.
