摘要
为了测试载波伪距单点定位的定位精度,本文建立了GPS载波伪距单点定位的无电离层组合观测方程,设计开发了GPS载波伪距单点定位程序,读取广播星历文件和观测值文件,完成卫星位置计算,最后输出观测文件中GPS卫星的坐标文件、观测文件中连续观测到的卫星坐标文件以及坐标值及改正坐标文件,逐个实现各个函数模块的功能,为实际精确定位工程提供理论基础。
In order to test single point positioning and briefly introduces several kinds of carrier phase of a linear combination of the single point positioning observation. This paper built the procession of pseudo range single point positioning of GPS carrier and ionosphere combination observation equation. And designed and developed with single point positioning program,this program reads the broadcast ephemeris files and observations,complete satellite position calculation,satellite selection,parameter estimation,the final output file GPS satellite coordinates file,file continuous observations of satellite coordinates file and coordinate values and correction coordinates,design thought based on the modular programming,the function of the realization of each function module one by one. It provide a theoretical basis for accurate positioning for the actual project.
