摘要: 文章阐述了空间交会最终平移段的制导设计方法。在最终平移段 ,追踪航天器沿视线方向作受迫运动 ,逼近目标航天器对接部位 ,追踪航天器相对速度的变化一般考虑指数型与等速型两种模式 ,采用分段制导策略。由追踪航天器相对运动轨迹及速度变化率确定机动加速度 ,在工程上采用多次有限常推力机动方式或多次冲量机动方式

Abstract: The design method of the guidance strategies for the final translation of space rendezvous is investigated in this paper. In the final translation, the chaser makes straight line forced motion with a give relative velocity profile, in terms of which the maneuver acceleration can be derived, and N-thrust and multi-pulse propulsion can be used in engineering projects.
