GPS技术在水库施工控制网测量中的应用

The Application of GPS technology in control network measurement of the reservoir construction

本文结合在锦凌水库枢纽工程施工控制网测量中得到的C级GPS网测量成果,对施工控制网的布网方案、施测方法、平差计算及精度分析做了详细的介绍,并对该控制网成果进行了分析。详细论述GPS网的测量精度,并提出GPS定位技术用于高等级施工控制网测量的方法和注意事项。

In this paper, combined with the Jinling reservoir control network construction survey obtained in the C-class GPS network measurement results, the control network of distribution network solutions, measurement method, adjustment calculation and precision analysis made a detailed presentation, and the net results of the control were analyzed. Using the obtained results and adjusted GPS-RTK technology to do section measurements and mapping of Daling river. The measurement accuracy of GPS network is discussed in detail, and the methods and precautions of GPS positioning technology for high-grade construction control network measurement are proposed.
