摘　　要：在对GPS高程测量的原理和方法进行初步的探讨的基础上,结合工程应用实际,以数值拟合为主,建立了高程转换的数学模型,同时用VB开发了GPS高程控制转换系统,经试实验测试得出了一些参考性的结论。In this paper, the principle and method of GPS height measurement are studied.then with a mathematical model of height conversion which mainly to numerical fitting is established combining the practical application of engineering. Meanwhile, a GPS height conversion system is established by VB. Some reference conclusions are reached after some testing experiments with this system.
