| 摘 要： | 研究近地轨道卫星沿航向跟踪空间非合作目标的相对轨道确定问题。首先给出以追踪星与非合作目标轨道根数差分描述的相对运动方程;其次根据星间测量几何关系对应的测量方程,提出一种新的基于两步估计的相对轨道确定方法;最后通过数学仿真验证了收敛速度快于扩展卡尔曼滤波,并对初始状态的选取不敏感,具有一定鲁棒性。

| Abstract: | Firstly,the relative motion equation between the chaser and the non-cooperative target was presented in the form of orbit elements difference.Secondly,based on the measurement equations,a novel relative orbit determination method was proposed using two step estimation.The effectiveness of the proposed method was verified by the simulated experiment. |
