Abstract: Zi Yuan 3(ZY-3) is the first civilian high resolution stereo mapping satellite in China. The attitude control system of ZY-3 is introduced. By calibrating the relative reference of star sensor and applying the star sensor and gyro integrated filter, the high accuracy of attitude determination is achieved. High stability of three-axis control is realized by adopting a structure filter and using the feedforward compensation of magnetic unloading torque. The largeangle roll maneuver is achieved by using trajectory planning. Based on on-orbit data of ZY-3 satellite, the implementation of specific indexes is proposed. Furthermore, the scheme of control system is tested on orbit.
