| 摘 要： | 针对GEO卫星几何法定轨中系统误差对PDOP值的影响进行研究,首先回顾了经典几何法定轨的基本原理,然后根据顾及系统误差的几何法定轨原理推导出PDOP值计算公式,并利用5个跟踪站的模拟数据,计算了多种系统误差情况下PDOP值。结果表明:系统误差对GEO卫星几何法定轨的PDOP值影响很大;采用顾及系统误差的几何法定轨方法可以较好地削弱系统误差对PDOP值的影响;国外布设跟踪站比仅在中国布设跟踪站能更好地削弱系统误差对PDOP值的影响。

| Abstract: | Effect of systematic error on Position Dilution of Precision(PDOP) of geometry orbit determination for Geostationary Earth Orbit(GEO) satellite was discussed.Firstly,the fundamental principle of classical geometry orbit determination was reviewed;secondly,the formula calculating PDOP was deduced by the method of geometry orbit determination with systematic error;thirdly,PDOP with multi systematic errors was computed by simulated data from five tracking stations.The result showed that the influence of system... |
