Application of the Simulation of GPS Height Solving Overhead Transmission Line Height Control Measurement

本文通过实例分析,在没有重力勘测资料和地球重力场模型的情况下,利用GPS高程拟合解决架空输电线路工程的高程控制测量,从而满足架空输电线路工程中平断面图的高程测量精度要求,以及为提高GPS高程拟合精度所需要注意的若干问题进行分析和探讨,为更好地应用GPS解决高程控制测量问题提供了有利的借鉴和宝贵的经验。

This article analyzed the examples, without data of gravity survey and the earth gravitational field model, application of the GPS height simulation solve overhead transmission line height control measurement. That satisfy the precision requirement of height measurement in the plane of circuitry engineering. For improving the precision of GPS height simulation, analyze and discuss several questions that should be payed attention to. The article will provide useful and quotable experience for applying GPS to solve several questions of height control measurement.
