A yaw attitude determination method based on coarse sun sensor information for the GEO satellite

Abstract The coarse sun sensor is used to measure the satellite’s attitude relative sun. If satellite can maintain earth-pointing by high-precision sensor, information be determine yaw attitude, which effective in coping with short-term failure of sensor. This paper proposes a method using information. In view main factors affecting accuracy measures improve are proposed: calibration based on historical data and measurement range selection. Simulation onboard data, expected function achieved, correcting significantly improved.
