多组GPS卫星广播星历轨道标准化的研究

Standardization of the GPS Satellites Orbits by Using Several Groups of GPS Broadcast Ephemeris

介绍了多组广播星历的轨道标准化的两种方法,通过对观测时段较长的同一GPS卫星多组广播星历分析,提出了整体轨道拟合方法进行GPS卫星轨道标准化,试验结果证明整体标准化方法优于分段标准化方法。

This paper introduced two methods for standardization of multiple broadcast ephemeris tracks, through analysis of the same GPS satellite broadcasting ephemeris by long hours of observation and proposed GPS orbits standardization using the overall orbital fitting method. The test results show that overall standardized method is better than subparagraph standardized methodology.
