| 摘 要： | 近年来人们往往利用GPS／重力来确定正常高，但正常高不同于表示绝地高程的正高，为此，笔者在GPS／重力确定正高方面作了一些研究，对由似大地水淮面转换成大地水淮面公式的意义及其误差，以及如何提高正高度精度都作了讨论，这于山区开发会有益的。 |
| 关 键 词： | GPS 重力 垂直梯度 正高 等位面 大地水淮高 高程异常 水淮测量 |

| Abstract: | Recently utilizing GPS/gravity to determine the normal height were adopted by some geodetics.But nermal height is different from othometrie height represented the absolute height.Based on above fact the author make some research,which include determining the orthometric height used the GPS/gravity,discussing the meaning of formala transforming geoid to quasigeoid and its error and how to raise the orthometric height pricision.These are benefit to develop mountain area. |
| Keywords: | GPS gravity gradient of gravity orthometric height |
