摘要： 针对编队小卫星间的相对飞行特点,在Hill方程描述编队飞行小卫星间相对运动的基础上,提出利用星间无线电测距的相对自主定轨,来获得环绕小卫星精确轨道的卫星定轨方法。通过具体仿真计算,并与小卫星GPS自主定轨方法相比较。仿真结果表明,此方法确实有效。

Abstract: It uses Hill equation to depict the satellite movement of relativity and utilizes the ephemeris data received from satellite transponder to obtain the mutual distance. Through the simulation, which is compared with GPS autonomous orbit determination for the Moonlet, it indicates that this approach is effective and can realize moonlet precise orbit determination.
