精密单点定位精度分析

Analysis the Precision of Precise Point Positioning

利用武汉大学自主研发的精密单点软件Trip对试验区7个像控点,5个国家等级三角点GPS数据进行处理,比较了IGS以及CODE公布的30s间隔的精密钟差数据处理的结果,同时比较了分别采用快速星历和最终星历进行数据处理的结果,并将精密单点定位解算结果与差分定位结果、国家三角点作比较分析。

Using the precise point positioning software trip which is developed by Wuhan University to process the GPS data of seven control points and 5 triangular points of national level. Comparing the results processed with the 30s clock file published by IGS and CODE. At the same time, comparing the results processed with fast and final ephemeris data. The results processed by precise point positioning are compared with the results processed by differential positioning, and 5 triangular points of national level.
