| 摘 要： | GPS高程测量技术一直未得到充分应用。结合实践经验，利用多年来在工作中积累的GPS观测数据及高程测量数据，通过对GPS拟合高程与水准测量高程进行精度分析．为利用GPS高精度观测值加高程已知点来拟合求得待定点高程的理论提供了依据，从而达到用GPS技术代替低等级水准测量的目的。

| Abstract: | The technique otGPS elevation hasn＇t been fully used in surveying. Based on the practical experience,we carried on the precision analysis of the GPS planned elevation and the leveling elevation with a lot of dala accumulated in works. The analysis provides technical reference for the theory of adding GPS measuring value to the known point to get the elevation of the unknown point. So the technique of GPS may take the place of lower grade leveling. |
