| 摘 要： | 随着IGS星历产品的种类和精度不断提高,精密单点定位对星历有了更多的选择。本文对IGS星历和广播星历进行了精度对比,同时介绍了相位平滑伪距的原理,着重通过对伪距单点定位和相位平滑伪距单点定位与广播星历I、GU星历和IGS最终星历的组合对国内IGS跟踪站(shao)进行单点定位的分析,证明了伪距平滑后的定位精度有了明显的提高,使用IGU星历比广播星历定位精度也有所提高。

| Abstract: | As the IGS product range and ephemeris accuracy increased,which make ephemeris used in precise point positioning have more choice.This paper analysis of accuracy of IGS ephemeris and broadcast ephemeris,introduced the principle of carrier phase smoothed pseudorange.Focused on analysing of accuracy of point positioning using carrier phase smoothed pseudorange and nosmoothed pseudorange with various ephemeris,this paper show that the positioning accuracy with smoothed pseudorange have improved,and the precisi... |
