| 摘 要： | 对于非合作目标，由于中远距离星上相对测量手段有限，大多情况仅能获得视线角信息.仅视线测量相对导航方法在GEO轨道条件下滤波精度低、可观测性差.提出一种基于星间视线方位测量和轨道预报信息结合的非合作目标相对导航方法.建立基于星间相对运动模型的状态方程和基于星间视线测量和轨道预报信息的观测方程，分别选取了扩展卡尔曼滤波和无迹卡尔曼滤波两种方法，仿真分析了轨道预报信息精度和滤波方法对导航精度的影响.

| Abstract: | For noncooperative objectives, with limited measuring method, only angle measurement information can be achieved for the mid long distance satellites. The line of sight measurement relative navigation algorithm has low precision and observability for GEO satellites. Based on the combination of line of sight inter satellite measurement and orbit forecast information of ground measurement, a method of relative navigation algorithm for GEO noncooperative satellites is presented. The system state equation based on the inter satellite relative motion model is established. The measurement equation is established based on LOS and orbit forecast information. EKF(extended Kalman filter) and UKF(unscented Kalman filter) methods are adopted. The effects of orbit forecast information measurement accuracy and filtering methods on the navigation accuracy are illuminated via the simulation and analysis. |
