If the Geoid or quasi-Geoid model is given, GPS can be used directly to determine orthometric height or normal height, which can take the place of the traditional geometric leveling and make the separation mode of plane control network and elevation control network in traditional geodesy become a history.
在高精度、高分辨率(似)大地水准面模型的支持下,利用GPS技术可以直接测定正高或正常高,从而取代传统繁琐的水准测量方法,使得平面控制网和高程控制网分离的传统大地测量模式成为历史。

This paper puts forward, in the point, gravimetric geoid method, geometric geoid method and synthesis method to transform ellipsoid height into orthometric height.
基于此，扼要提出应用重力大地水准面法、几何大地水准面法和综合法将GPS椭球高改化为正高的方法。
The accuracy of Orthometric Height will be directly affected by ellipsoidal height precision during GPS height transformation, therefore, the detection of gross error is very important.
GPS高程转换中，大地高的精度将直接影响转换后正常高的精度，为此大地高的粗差探测是比较重要的一个环节。
