The invention discloses a space station accompanying satellite inertia release system and method based on a child-mother type satellite, and belongs to the technical field of micro-nano satellite in-orbit deployment. A mother satellite does circular motion around the z axis of the mother satellite, when the needed angular speed is reached, a child satellite is released, and the mother satellite stops rotating; after a specified number of sub-satellites are released, a slightly large angular acceleration is given to the mother satellite, and meanwhile, due to the connection of the tethered system, the mother satellite can be conveniently released and withdrawn in a relative space station coordinate system; the system can accurately control the position and the speed of an initial relative space station coordinate system of the space station accompanying micro-nano satellite, so as to meet conditions required by orbit convergence under specific conditions; the child satellites can timely return to the mother satellite to supplement energy and upload existing task data to reduce the memory demand and the energy demand of the child satellites; the release principle adopted by the system is simple, execution is stable, faults are not prone to occurring, and good popularization value is achieved.

    本发明公开了基于子母式卫星的空间站伴飞卫星惯性释放系统及方法,属于微纳卫星在轨部署技术领域,母卫星绕自身z轴做圆周运动,达到需要的角速度时释放子卫星且停止母卫星转动,由于惯性子卫星被甩出,释放指定数量的子卫星后给予母卫星略大的角加速度,同时由于绳系的连接,母卫星在相对空间站坐标系下的释放与收回均可便捷地实现;本系统可以精确控制空间站伴飞微纳卫星的初始相对空间站坐标系的位置与速度,以满足特定情况下轨道收敛需要的条件;子卫星可及时回到母卫星补充能源并上传已有任务数据减少子卫星内存需求与能源需求;本系统采用的释放原理简单,执行稳定,不易出现故障,具有良好的推广价值。
