Function test results of an adaptive attitude control system of the Data Relay Test Satellite (DRTS) that was launched on September 10, 2002 are summarized in this paper. The purpose of the adaptive attitude control system is to compensate for attitude disturbances caused by motion of an inter-satellite communication antenna. The control system estimates mass property parameters and improves attitude accuracy when the antenna motion effects are mainly cancelled by feedforward control. The estimation accuracy of the mass property parameters is improved with the antenna motion even when the initial estimation accuracy is not enough. The function tests confirmed that the attitude control system realizes almost the same performance as predicted on the ground. Since the accuracy of the feedforward control is easily improved by adopting the adaptive attitude control system, this system is effective for attitude control of spacecraft with mobile bodies like antennas.
