Abstract: Firstly, the relative motion state equations were described in line of sight coordinate frame. And the artificial potential function guidance was used for autonomous rendezvous and docking  with a non-cooperative target spacecraft and dynamic obstacle avoidance missions. Then, mission of autonomous rendezvous and docking with the non-cooperative target was accomplished and dynamic obstacle avoidance was studied by potential function guidance. Secondly, the stability of the method was analyzed and proved by Lyapunov theory, and the effects of two different dynamic obstacle avoidances were studied and discussed. Meanwhile, the capability of potential function guidance was analyzed. Finally, the numerical simulation results based on a precise mathematic model demonstrate the validity and effectiveness of the proposed guidance method.
