Abstract: Considering the characteristics of closerange rendezvous and docking, an idea of using guidance impulse to determine the safety belt in rendezvous and docking is presented. Four belts, including the uncontrolled belt, the modified belt, the guarded belt and the urgency belt of retreat, are designed near the standard trajectory. The guidance strategy based on safety belt is also designed. The simulation results indicate that the guidance strategy can detect a part of fault immediately, and consume less fuel. It is a guidance strategy which is good at both of fuel consuming and trajectory safety.

Key words: rendezvous and docking, safety belt, guidance
