Multi-satellite responsive inspection mission planning with multiple constraints

Multi-satellite responsive inspection mission refers to the fact that multiple target satellites appear unknown, and the inspection service platform carries out orbit transfer within a short period of time, and carries a number of sub spacecraft to perform overflight inspection on the targets. For mission planning of this kind of problem, the platform phasing strategy based on coplanar maneuver was firstly presented and a screening calculation model of inspection window satisfying the constraints of illumination and maneuvering ability was established. Secondly, a greedy search and multi-round planning method was proposed to determine the task assignment scheme and inspection order. Finally, this method's effectiveness was tested under high precision orbit model and it was compared with hybrid en-coding genetic algorithm. In the example, the optimization effect of this method is slightly better than that of hybrid en-coding genetic algorithm and the efficiency is about 227 times of the latter, which indicates that greedy search algorithm and multi-round planning method are more suitable for solving this problem efficiently.
