Abstract:

Distant Retrograde Orbits (DROs) 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. It is thus needed to analyze the close relative motion in DROs and furthermore develop close formation designs. Based on the Floquet theory, a fundamental solution for linear relative dynamics in DROs is obtained. A natural formation is designed based on the natural periodic solution for the linear relative dynamics. Characteristics of the natural formation are analyzed. Moreover, non-natural formations for fast circumnavigate is designed with impulse maneuvers. The fuel consumption of different types of circular reference orbits are analyzed to guide formation designs. Finally, a type of reference trajectories is designed for transfer between two arbitrary positions with safety guaranteed.

Key words: circular restricted threebody problem, distant retrograde orbits, relative motion, formation design, Floquet theory
