摘要: 远距离逆行轨道是地月空间中一族稳定的周期轨道,适用于地月空间站等长期任务。为维持任务的长期存在,交会对接及编队飞行等任务往往是必要的。因此有必要分析远距离逆行轨道上的近距离相对运动解,并进行编队设计。首先,基于Floquet理论得到了远距离逆行轨道上的近距离线性化相对运动的基础解集,并对其解进行了分类与分析。其次,以基础解集中的自然周期解为基础设计了伴飞编队,并对其特性进行了全面分析。之后,针对圆形受控绕飞编队做了详细的分析,可用于指导后续受控编队的设计。最后,设计了两点之间的安全转移编队,可用于任意两点之间的转移,并保证转移过程中主星与副星之间具有足够的安全距离。

Abstract: Distant retrograde orbits (DRO) are a kind of periodic orbits in the Earth-Moon system. DROs are appropriate for long-term missions due to favorable stability. Rendezvous and docking is a basic technology for the supplement of long-term missions, as well as close formation flying for some flying-around tasks. Therefore, the close relative motion in DRO are analyzed and furthermore close formation designs are established. Based on the Floquet theory, a fundamental solution of linear relative dynamics is obtained. A natural formation is designed based on the natural periodic solution of the linear relative dynamics. And characteristics of the natural formation are analyzed in details. Moreover, non-natural formations for fast circumnavi-gate is designed with impulse maneuvers. The fuel consuming of different types of circular reference orbits are analyzed comprehensively to guide the formation designs. Finally, a type of reference trajectories is designed to transfer between two arbitrary positions with safety guaranteed.
