| 摘 要： | 简单介绍了利用BERNESE5．0软件精密单点定位的计算流程，分析了IGS目前提供的各种精密星历的精度和时延性，根据实验数据进一步比较了超快速星历和最终星历对精密单点定位精度的影响。结果表明，利用IGS的超快星历也可以达到厘米级定位精度，从而为城市静态GPS控制网和网络RTK测量提供了有益的补充。

| Abstract: | Process of Precise Point Positioning(PPP)using Bernese GPS software versions 5.0 is simply introduced,precision and delay of every precise ephemeris products from IGS are analyzed,furthermore,the influence of ultra-rapid precise ephemeris and final precise ephemeris on PPP is compared base on test data.The result show that,the cm-level of GPS position can be achieved using ultra-rapid precise ephemeris,so that would be a beneficial supplement to survey of urban GPS control network and RTK. |
