摘　　要：给出了模型拟合法进行GPS高程转换的数学模型以及顾及地球重力场模型影响的移去-恢复法在GPS高程转换中的应用,并结合实际指出了GPS高程转换中所应当注意的问题.利用Visual C++6.0开发了一套比较实用的GPS高程转换软件包GPSH(global positioning system height transformation),该软件可利用水准高程和水准高差观测值进行GPS高程转换,并给出了软件的整体框架和主要功能.最后利用该软件处理了某一线路的GPS水准测量数据,获得了比较满意的结果.The approach and mathematic model of GPS height transformation, and the application of remove-store approach based on Earth＇ s gravity field model in GPS height transformation are researched. The matters of GPS height transformation which need attention are illustrated. The practical software package GPSH is developed on the basis of Visual C ＋ ＋ 6.0, which is used for transferring the GPS geoid height by the leveling height and leveling height difference observations, and the integral frame and main function of software are shown . Finally a GPS leveling case is processed by GPSH and satisfying results are gained.
