| 摘 要： | 针对单颗卫星对空间非合作目标的纯测角跟踪定轨系统存在观测几何条件差和定轨误差较大的缺点,提出利用双星编队对空间非合作目标进行协同观测。该方法引入平方根无迹卡尔曼滤波(UKF)算法,并融合地面站观测双星编队信息、双星编队星间测量数据以及双星编队对空间目标光学观测信息进行整网定轨,实现在纯测角条件下双星编队对空间非合作目标的实时跟踪。仿真结果表明该方法可以改进观测几何条件和提高空间非合作目标的跟踪定轨精度。

| Abstract: | For a single satellite to a non-cooperation space target(NCST) passive tracking using bearing-only measurements,the observation geometric condition is bad and the orbit determination accuracy is poor.To solve this problem,the two-satellite formation's coordination observation to the NCST method is proposed.The integrated orbit determination with the square root unscented Kalman filter(UKF) algorithm is adopted based on fusion of the two-satellite formation's groundbased observation information,inter-satelli... |
