| 摘 要： | 以恒星和地球方位矢量夹角作为观测量,用迭代最小二乘法为滤波算法来确定历元时刻的状态,并以预报方式实现自主导航的方法研究多航天器部署问题中被动段导航问题.通过数学仿真,分析比较了采样周期、采样弧长、敏感器精度、恒星方位等因素对于定位精度的影响,总结了其变化规律,并给出了安装因素对于导航精度的影响.与测量因素相对比,结果表明前者对导航精度的影响更大.

| Abstract: | In this paper,the autonomous navigation method based on the earth sensor and the star sensor on passive section during the multi-satellites mission is studied.The orbit prediction is given by the initial state which is determined by least square method.Digital simulations are conducted to analyze the influence of sampling period,measured arc length,accuracy of measurement,reference star positions and installation errors on the position accuracy.It is indicated that the effect of measuring errors is greater than the installation errors. |
