厂区GPS控制网起算点的分析与处理

摘要

本文介绍了在GPS控制测量中对起算点分析和处理方法，提出了一种在联测起算点前对起算点投影变形的概算新思路，并给出了厂区GPS控制测量起算点分析和处理的完整流程，最后以一个工程实例进行了验证。% This paper introduced the analysis and processing of initial points in the GPS control survey, and then raised a new thought on the estimating method about projection length deformation of initial points and draw up the flow chart of the analysis and processing of initial points, finally through an engineering project , this method was verified.
