摘要
GPS高程测量有着它自身的难点,这就是大地水准面定位.本文简单地介绍了研究大地水准面的三种主要方法,及利用GPS高程测量成果结合的表拟合技术求正高高程应用的情况.
GPS (Global Positioning System) height measurement has its problems, regarding for example geoid determination. This paper reviews the three main methods of studying geoid and discusses the orthometric height accuracies obtained by combining GPS ellipsoidal height determination results with the surface fitting technique (or a geometric interpolation method).
