北斗导航卫星位置计算方法研究

摘要

为了提高北斗卫星轨道的精确性和实时性，在分析星历文件中的开普勒轨道参数和轨道摄动参数的基础上，阐述了卫星轨道计算方法，用Visual C＋＋语言编程实现了卫星轨道位置计算，并用2013年1月13日的北斗导航文件计算出1、5号GEO 卫星和6、9号M EO/IGSO卫星位置及其它们外推时刻卫星的位置，通过对比分析，验证了该算法的可行性。%In order to improve the accuracy and real-time of Beidou satellite orbit ,The Kepler orbit parameters and orbital perturbation parameters of the ephemeris files were ana-lyzed ,then the algorithm of satellites orbit were discussed ,The satellite orbit position is cal-culated by using Visual C+ + programming language ,and the satellite position and their ex-trapolated time satellite position were computed whose No .1 ,5GEO satellite and No .6 ,9 M EO/IGSO of the Beidou navigation document from January 13 ,2013 ,through comparing and analyzing ,the feasibility of the algorithm were verified .
