GPS控制网平差方案选择及成果分析

The Method Selection and Results Analysis of GPS Control Network Adjustment

如何将GPS基线向量归算到原有地面网点所属的基准 ,这是应用GPS技术建立或加密控制网的一个重要问题 ,为此应根据原有地面网的实际情况及不同的要求选择合适的平差方法。本文以大水坡GPS网为例 ,说明仅采用地面网的起算数据 ,在地面网的坐标系统中进行GPS网平差的方法 ,并对平差成果作多方面的分析比较。

How to reduce GPS basis to the initial datum of the plane network,it is an important problem for using GPS technology to found or densify control system,for this reason we adopt the suitable adjustment methods according to the actual situation and various demands of the original plane network.This paper takes Dashuipo GPS network as an example that only adopting the original data of the plane network and the adjustment method of the GPS network in the plane control system,moreover analysing and comparing the results in many ways.
