摘要
介绍了精密单点定位的基本原理,对IGS精密星历进行了研究,利用Waypoint8软件对精密单点定位精度进行了测试与分析。结果表明:GPS精密单点定位在NEU三维分量上的精度约为20cm。
The principle of Precise Point Positioning (PPP) is introduced, and study on IGS precise ephemeredes, has tested and analyzed the precision of PPP using the Waypoint8 software. Experiments show that the precision of PPP excelled 20cm on the direction of NEU.
