| 摘 要： | 根据航天器相对运动的C-W-Hill方程建立的动态模型,以及基于无线电测量方案建立的相对距离观测模型,提出了一种用扩展卡尔曼滤波(EKF)确定分布式航天器相对轨道的方法。用STK、Matlab软件进行的仿真验证结果表明,该方法可确定分布式航天器相对位置和相对速度,所获解的精度较高。

| Abstract: | A determination method of relative orbit for distributed spacecrafts by Klman filtering was put forward according to the dynamic model founded by C-W-Hill equation that concerned relative movement between spacecrafts,and the observation model of relative distance based on wireless measurement in this paper.The simulation using STK and Matlab software showed that the determination of the relative position and velocity for distributed spacecrafts would be realized,and the accuracy of the solution was high. |
