GPS网平面基准点的可靠性分析

The reliability analysis of datum points in GPS network

通过具体实例,对GPS网约束平差结果进行了分析、比较,并提出了GPS网平面基准点的可靠性检验方法,得出了作为起算数据的基准点及其点位误差对GPS网约束平差精度的影响规律。

The reliability of datum points is very important to surveying result of GPS network. This paper analyzes and compares the result of bind adjustment of GPS network through concrete examples, under statistical inspect. The paper put forward a simple means for testing the reliability of datum points, gives the influence rule of datum points and their position errors to the precision of bind adjustment of GPS network.
