摘要
为了从GPS测量数据中获取点位正常高信息,选择几种不同的GPS高程拟合模型进行实验分析,并与传统水准测量精度进行比较,得出如下结论:GPS高程拟合得到的正常高可以达到cm级精度,对传统的几何水准测量具有参考价值。
In order to obtain normal height information of point from GPS measurement data, choose some different models of GPS elevation fitting to experiment, and compare the accuracy with the traditional measuring, the following conclusion is obtained： the normal height which gets from the GPS elevation fitting can reach cm level precision, and it supplies reference to the traditional geometric leveling.
