摘要
阐述了在高原矿区建立独立GPS控制网时如何通过几种椭球变换的方法获得GPS控制网起算点坐标的方法,并通过某矿区D级GPS控制网的建立,比较几种椭球转换方法的特点及其对GPS网二维约束平差精度的影响。
This paper expounds how to obtain starting points＇ coordinates of GPS control network by means of several ellipsoid transformation methods when setting up independent GPS control network in plateau mine area. By the estiblishment of a GPS D-level contral network, the characteristics of several ellipsoid transformation methods and their imfluence on the accuracy of two-dimensional constrained adjustment of GPS network are compared.
