| 摘 要： | 精密单点定位的实质就是利用精密星历和精密卫星钟改正来实现定位。但是IGS不同分析中心提供的精密星历和卫星钟改正数的基准不一致，如果使用不同分析中心提供的精密星历和卫星钟差就会对定位精度产生影响。本文采用IGS精密星历和JPL精密星历，使用相同的IGS精密卫星钟差，分别计算对测站坐标精度的影响。

| Abstract: | Using the precise ephemeris and the precise satellite clock correction can realize the precise point positioning(PPP).The precise ephemeris and the precise satellite clock correction provided by the different analysis centers is inconsistent.Using the precise ephemeris and the precise satellite clock correction which the different analysis center provides have the influence to the precise point positioning.The precision influences of the surveying station coordinate is compared to use the IGS precise epheme... |
