摘　　要：近年来,GPS高程方面的研究是一个热点,能否利用GPS水准代替常规的水准测量是人们关注的问题之一。在介绍GPS水准原理的基础上,论述了高程拟合的方法,并根据这些方法进行了计算分析,说明这些方法在GPS高程拟合中是可行的。Studying GPS height is a hotspot problem recent years. Whether GPS leveling will substitute common leveling or no is an important problem that people concerned. This paper introduces the principle of GPS leveling. It elaborates the methods of GPS height fitting. Then the author computed and analyzed on the base of real surveying data by using the methods. As a result, some beneficial conclusions have been achieved.
