地球局部重力场对近地卫星轨道的影响

THE EFFECTS OF LOCAL GRAVJTA-TIONAL FIELD ON THE ORBIT OF A NEAR-EARTH SATELLITE

本文重点探讨了近地卫星的受力情况,从理论上分析了司托克斯积分公式的一些特性,给出了高空扰动引力的误差量级及适当的近区域积分半径;最后,利用数值积分方法,对几种情况的卫星轨道计算进行了比较分析。

This paper will emphasis upon analyzing the effects of various force on the near-earth satellie. Some properties of the Stockes formula are analyzed theoretically.The errorlevel in tn the computalion of upper-air gravity disurbances as well as reasonable integral radius of near area are given And finally, the resulls of the satellite orbit computed with a numerical integration method in several cases are compared and analyzed in this paper.
