Abstract: The problem of trajectory and attitude control for a chaser to approach to an uncontrolled rotating target satellite is researched in this paper. Based on the orbit and attitude dynamics equations of two relative motion spacecrafts with arbitrary eccentrics, the reference trajectory and the attitude for a chaser to approach to an uncontrolled rotating target are analyzed and designed, and a kind of adaptive sliding mode controller is proposed for the six degree of freedom position and attitude control. The simulation results shown that the reference trajectory and attitude designed are reasonable, and the adaptive sliding mode controller is effective.
