摘　　要：GPS是随着现代科学的发展而兴起的以卫星为基础的无线电导航定位技术。它具有定位精度高、操作简便等优点,在测量领域获得了越来越广泛的应用。GPS在高程控制测量方面的应用还存在着不尽如人意的地方,主要的原因是GPS高程控制测量只能得到大地高,而不是工程中所需要的正常高。实现大地高向正常高的转换是工程上应用GPS高程控制成果所必须要解决的问题,也是本文研究的主要内容。GPS rose with the development of modern science and was the satellite-based radio navigation and positioning technology. It has high positioning accuracy, the advantages of simple operation, the increasingly wide application in measuring areas. There are unsatisfactory in application of GPS height control survey, mainly because GPS height control survey can only get geodetic height, but not the normal height required within the project. Achieving high conversion is a problem that should be resolved on engineering applications of GPS to normal height control.
