| 摘 要： | GPS高程测量代替常规水准测量的技术和方法已经成为这些年来许多大地测量学者们研究的热门课题之一，本文简单地介绍了GPS高程测量的模型及其适用范围，并通过在也门Block 69的应用分析，说明了在高程异常值变化平缓的平坦地区，只需测定少量（不少于3个）较均匀分布于测区的已知高程控制点，采用平面拟合法，拟合精度就能够达到测区测量精度的要求。

| Abstract: | The technical of GPS height survey instead of normal leveling is one of the popular subjects which are studied by many geodetic survey scholars.This article introduces model and scope of GPS height survey.It shows that the tabular surface fitting accuracy is required to survey accuracy of the project in the value of height normal no bigger change area by survey few known and equable distribution height control points(no less than three points) through the application and analysis in Yemen Block 69. |

| Keywords: | GPS height survey parameter of model tabular surface fitting quadratic surface fitting |
