大型GPS网拟合高程与水准高程的比较与分析

摘要

就目前技术而言,GPS高程控制的应用范围受到了一定的限制。本文讨论了GPS拟合高程和水准高程的方法,通过实例计算进行了精度对比和分析,其结果表明,GPS测量可以代替传统水准测量,提高了生产效率。%The application of GPS elevation control is currently limited technically.This paper discusses the method of GPS fitting elevation and leveling elevation,analyses and compares their accuracy through instance calculation.The result shows that GPS control elevation survey can take the place of conventional leveling and improve production efficiency.
