基于网络RTK的无人测量船在填海工程中的应用

Application of unmanned survey boat based on network RTK in reclamation project

以香港国际机场第三跑道填海工程使用的OceanαSL40全自动无人测量船为例,介绍了无人测量船系统利用香港卫星定位参考站网进行网络RTK无验潮水深测量的基本原理和作业流程,展现了基于网络RTK的无人测量船系统较高的测量精度及其在特殊水域环境下良好的适应性,为填海工程的水深测量方法提供了更丰富的选择。

This paper takes the OceanαSL40 autonomous unmanned survey boat used in the main reclamation works of Hong Kong International Airport three runway system project as an example to introduce the basic principles and workflow of the unmanned survey boat by using Hong Kong satellite positioning reference station network to conduct network RTK for bathymetric survey without the tide gauge.It shows that the unmanned survey boat system based on network RTK has a higher measurement accuracy and good adaptability in a special marine environment,which could provide more choices for the bathymetric survey of reclamation projects.
