关于卫星网整网自主定轨方法的探讨

A discussion on satellite-network autonomous orbit determination

随着在轨卫星数量的不断增多 ,卫星网的自主定轨已经成为迫切需要。本文重点阐述如何利用星间相对测量 (相对距离测量和相对速度测量 )技术 ,将卫星精密轨道确定方法和大地测量中的整网平差方法相结合 ,来实现卫星网的自主定轨。仿真结果表明 ,这一方法是切实有效的。

With the increasing of satellite quantity,the traditional orbit determination scheme can not meet the factual requirement.In this circumstance,a method for satellite net autonomous position determination is needed urgently.Actually,we can utilize the relative survey information to achieve this purpose.By means of some specifically data blending method,realizeing satellite net autonomous position determination and improving position accuracy become feasible.With autonomous position determination technology it becomes possible for the satellite net to autonomously navigate itself in a period of time without the ground support.To testify the validity of this paper,simulation results and analysis are given.
