摘要： 从满足重力卫星编队的轨道根数条件出发, 通过全过程动力法仿真实验, 计算得出了满足串联编队(GRACE-type)、 钟摆编队(Pendulum-type)和车轮编队(Cartwheel-type)这三种卫星编队模式稳定在轨的轨道参数, 并验证了其稳定性。 同时, 深入分析了各种卫星编队模式对于重力卫星任务的适用性, 结果表明, 同时包含两个方向观测量的Pendulum-type编队和Cartwheel-type编队, 能够在一定程度上克服GRACE-type编队中存在的由单一星间观测量的强相关性导致的重力场各向异性敏感度问题, 是理论上更适合重力探测任务的卫星编队模式。

Abstract: Based on the condition of orbit elements that meet gravity satellite formation, we provide orbit elements which can meet the requirement of in-orbit stabilization of three types of satellite formation (GRACE-type, Pendulum-type and Cartwheel-type) by using dynamic method in the simulation experiment, and verify its stability. Meanwhile, we analyze the compatibility of different types of formation to the gravity satellite mission. It is concluded that, the type with observation on two directions, such as Pendulum-type (along-track and cross-track) and the Cartwheel-type (along-track and radium), will help to update the gravity anisotropy sensitivity problem caused by the high correlation of inter-satellite observation from GRACE-type satellite formation with only one direction. This type is proven to be the satellite formation more suitable for gravity satellite mission.
