摘要
在同一个标准的位置保持窗口内并置多颗卫星,并且避免相互之间的碰撞、干扰和遮蔽,是充分利用地球静止轨道资源的一种比较好的办法。针对我国卫星共位隔离的工程需要,文章提出了一种基于偏心率矢量和倾角矢量实现共位隔离的方法,给出了基于偏心率矢量和倾角矢量联合隔离的基本方法、约束方程,以及工程实现时的位置保持策略。通过仿真计算和工程实际应用,验证了该方法的正确性。
Nowadays,locating several satellites in a narrow station-keeping window is a good way to take advantage of the geostationary orbit source.a method of multi-satellite collocation using eccentricity vector and inclination vector is discussed in this paper.The principles and constraint equation of combined separation are investigated,which can be used to avoid collision,close approach and mutual interferences. The initial qualification,the eccentricity and inclination control strategy in E/W maneuver and N/S maneuver are given. Simulation results show that the minimum distance between the satellites is more than 10 kin, and two Chinese geostationary satellites are allowed to work in orbit with secure operation for several years with this separation strategy.
