4123 The Attitude Control Experiments of "HIT-SAT" and the Future Development Satellite

"HIT-SAT" is a small satellite to demonstrate performance of the bus systems of "Hokkaido Satellite". The main purpose of the attitude control system of "HIT-SAT" is to get basis data for the attitude control and determination system of "Hokkaido Satellite". "HIT-SAT" was launched on Sep. 23, 2006 by M-V-7. Attitude control system of "HIT-SAT" could get magnetometer data and gyro data on orbit. This paper describes the attitude determination from magnetometer data obtained on orbit.
