研究运行于椭圆轨道的卫星相对轨道确定问题,适用于配置有非合作测量敏感器的卫星。首先给出了以相对运动状态描述的椭圆轨道相对运动方程(T-H方程),并给出了解析解;其次根据星间测量几何关系对应的测量方程,提出一种新的基于两步估计的相对轨道确定方法;最后通过数学仿真对算法的有效性进行了验证。
To study the problem of determining the relative orbits of satellites operating in elliptical orbits, it is suitable for satellites equipped with non-cooperative sensors. Firstly, the equation of relative motion of elliptical orbit (TH equation), which is described by relative motion, is given and an analytical solution is given. Secondly, based on the measurement equation of geometric relationship of inter-satellite measurement, a new two-step estimation is proposed Orbit determination method; Finally, the validity of the algorithm is verified through mathematical simulation.
