摘要： 针对圆形轨道串行卫星编队进行研究,推导出满足开普勒轨道假设的相对运动方程,从物理概念上证明了这种描述关系的正确性;并在此基础上利用星间测量信息,设计扩展卡尔曼滤波器进行相对轨道自主确定,仿真结果验证了此相对运动方程与导航方案的有效性。

Abstract: A group of relative motion equations were given with the Keplerian motion assumption,which was proved to be true in physical concept.On the basis of these equations,an efficient approach for relative navigation of satellites flying in formation through inter-satellite measurements was developed,and an EKF was designed to estimate the orbit states of slave satellite.The simulation results verify the validity of these equations and the navigation method.
