卫星编队飞行相对轨道的确定

卫星之间相对轨道的确定对于多颗卫星编队飞行的控制和任务是十分重要的。结合空间圆形的编队飞行星座，本文给出了描述卫星近距离运动的C-W方程，讨论了空间圆形的编队卫星星座的构成，进而设定了利用激光仪测量星间位置矢量，并设计了Kalman滤波器来实现相对轨道的确定，分析和仿真结果表明，Kalman滤波器能够有效提高相对位置确定精度并给出相对速度的高精度估计。

The determination of relative orbit for satellites formation flying

The determination of the relative orbit between satellites is very crucial for satellite formation flying control.With the satellites circle formation as background,the C W equation in discrete time is derived,the measurement equation is given with the position coordinates as measurement variables,and Kalman filter is utilized for the estimation of relative orbit.The simulation and analytical results show that the Kalman filter is very effective in promoting the estimation accuracy of the relative orbit.
