一种交会对接轨迹安全带确定方法

针对近距离交会对接特点，提出一种由制导脉冲确定的交会对接安全带概念，在标称轨迹附近分别设计无控带、修正带、警戒带和紧急撤离带和基于安全带的制导策略.仿真结果表明，该制导策略能及时敏感部分故障，且燃料消耗不大，是燃料消耗和轨迹安全折中的一种制导策略.

Determination Method of Safety Belt in Rendezvous and Docking Trajectory

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.
