Abstract:

To address the task planning problem of parent-child spacecraft in orbit service under complex constraint conditions, the flight mission process of the parent-child spacecraft is designed. Firstly. Secondly, a two-level hybrid optimization method is proposed considering constraints such as time, lighting, and distance. The upper level of this method adopts an improved adaptive genetic algorithm to optimize the time nodes in different stages of the mission process. The lower level uses the multi loop Lambert algorithm, dual pulse control algorithm, and target correction method to optimize the flight trajectories of different stages under fixed time nodes in the upper level, thereby solving the problem of planning the approach observation mission process of parent-child spacecraft in different scenarios and reducing fuel consumption. Finally, the method is applied to two typical mission scenarios, and the feasibility and effectiveness of the mission planning algorithm design are further verified through simulation.

Key words: parent-child spacecraft, mission planning, two-level hybrid optimization method, adaptive genetic algorithm
