GPS卫星轨道摄动分析

Analysis on GPS Satellite's Perturbed Orbit

对影响ＧＰＳ卫星轨道的主要摄动量，即地球势函数Ｊ２项对ＧＰＳ卫星轨道的影响作出了定量分析，为我国建立自己的局部测控网获取精密星历提供依据。

Quantitative analysis on the main perturbation of the GPS satellite's orbit is given in this paper.The influence on the orbit is from the disturbing acceleration due to the term J2 of the earth's potential function. The results obtained make basis for getting precise ephemerides by means of building independent and local Chinese GPS monitor network.
