闹德海水库库区森林遮视严重，很难进行常规的三角测量，而采用ＧＰＳ定位技术，仅用很短时间就完成了库区横断面端点联网定位任务。作业过程中各项指标均优于规范规定的精度要求。实践证明，ＧＰＳ定位技术可以满足水库断面测量、地形测量、精度工程测量的要求。
The shelter in the Naodehai Reservoir Area is very serious and difficult to carry out routine triangulation. GPS positioning technology is used to complete the end-point network positioning tasks in the reservoir area in a very short period of time. During the operation, all the indexes are better than the standard requirements of precision. Practice has proved that GPS positioning technology can meet the requirements of reservoir section survey, topographic survey and precision engineering survey.
