摘要: 结合月球轨道交会对接任务的特殊性和中国探月工程的实际工程约束,介绍了嫦娥五号任务月球轨道交会对接远程导引轨道设计,包括轨道器调相和上升器远程导引两方面内容,重点介绍了月球轨道交会对接远程导引多脉冲调相轨道方案的选择、标称轨道优化设计、轨控策略和误差分析结果以及实际飞行轨道控制的情况。飞行实践数据分析表明:嫦娥五号任务月球轨道交会对接远程导引轨道设计是正确合理的,实际飞行的速度增量满足推进剂预算的要求,全飞行过程测控条件良好,交班点控制精度完全满足转自主控制的要求,有力保障了交会对接和样品转移的顺利完成。

Abstract: The phasing orbit design of the lunar orbit rendezvous and docking operation in Chang’e 5 mission is discussed in the paper, with consideration of the uniqueness of lunar orbit rendezvous and docking missions and the practical engineering constraints of China Lunar Exploration Program. The paper addresses the two aspects of the phasing orbit design, namely the phasing orbit designs of the ascent module and the orbiter, with the focuses on the multi impulse orbit scheme selection, nominal orbit optimization, orbit control strategy and error analysis.Moreover, the actual flight data of Chang’e 5 mission is provided to verify the correctness of the designs.
