GPS-RTK三维水下地形测量的应用与误差分析

摘要

In the GPS-RTK three-dimensional underwater topographic survey of the Hongkong-Zhuhai- Macao Bridge island and tunnel project, we analyzed the error by using the basic survey principles of GPS-RTK, made it gradually improved in the production practice, and constantly improved the water depth measurement accuracy, to meet the production needs of the project.%在港珠澳大桥岛隧工程三维水下地形测量中，应用GPS-RTK测量基本原理，对各项误差进行分析与研究，在生产实践应用中逐步改进，不断提高水深测量精度，确保满足其施工生产需要。
