| 摘 要： | 编队飞行卫星相对轨道的确定具有重要意义。本文提出一种完全自主的定轨方案,在利用星间测量信息实现编队飞行卫星自主定轨的基础上,引入太阳敏感器测量信息,利用扩展卡尔曼滤波算法提高环绕星相对轨道确定精度。仿真结果验证了这种导航方案和算法的有效性。

| Abstract: | Relative orbit determination for satellite formation flight is of great importance.The objective of this paper is to develop an efficient approach for autonomous relative navigation.On the basis of completing the orbit determination through inter-satellite measurements,the information of sun sensor is added to improve the performance of the estimation system,and the orbit states estimation is achieved through an Extended Kalman filter design.The numerical simulation results verify the validity of this navigation method. |
