摘要
为提高航天器在轨机动能力、工作寿命,升级扩大航天器功能,创造经济效益,近年来空间在轨服务与维护越来越成为空间技术的研究热点之一。为了降低地球静止轨道(GEO)卫星的发射成本,延长其在轨寿命,服务星采用“一对多”的方式为同一轨道平面上运行的多个工作星依次提供在轨服务。采用脉冲机动变轨与基于遗传算法的序列规划相结合的方法,利用霍曼转移、异面圆轨道转移和Lambert转移等算法建立数学模型,针对同面与异面服务两种情况进行仿真与结果分析,给出总脉冲速度增量最小的服务策略,为GEO卫星在轨服务任务规划提供参考。
In recent years,in order to improve the on-orbit maneuverability and working life of spacecraft,upgrade and expand the functions of spacecraft,and create economic benefits,on-orbit service and maintenance have become one of the hotspots in space technology research.In order to reduce the launch cost of GEO satellites and extend their on-orbit life,service satellites use a"one-to-many"approach to providing on-orbit service in turn for multiple working satellites in the same orbital plane.In this paper,the method of combining pulse maneuvering and genetic algorithm-based sequence planning is used to simulate and analyze the results of the same-plane and different-plane services.The mathematical model is established by using the Hohmann transfer,non-coplanar elliptical orbit transfer and Lambert transfer,and the service strategy with the smallest total pulse speed increment is given,providing reference for on-orbit service mission planning of GEO satellites.
