基于多冲量轨道机动控制,研究应用微小推力发动机来实现卫星编队轨道机动控制的方法。首先简单介绍轨道机动控制的多冲量次优解的求解方法,并把此方法的改进算法应用于卫星编队的整体轨道机动控制;为降低单次冲量值,应用小推力发动机实现轨道机动,提出了卫星编队多冲量轨道机动的路径规划方法,这种方法把一个多冲量轨道机动过程分成多个来实现;最后,数值仿真结果表明:该方法简便、实用,可以解决单次冲量值过大而不易实现的问题,同时对于轨道摄动因素的影响具有鲁棒性。

Path Planning for Satellite Formation's Multi-Impulse Orbit Maneuvers

Based on the multi-impulse method of orbit maneuvers, the method to enable the whole satellite formation to maneuver with micro-propulsion thrusters was studied in this paper. Firstly, the method of calculating near optimal multi-impulse for orbit maneuvers was introduced and applied to formation's orbit maneuvers. For using micro-propulsion thrusters, the idea of path-planning for the multi-impulse orbit maneuvers of satellite formation was presented, in which a multi-impulse orbit maneuvers course would be split into multiple courses. Last, numerical simulations showed that the method provided here was simple and practical, which could decrease each impulse to use micro-propulsion thrusters and be robust under the effect of various disturbances.
