GPS无验潮多波束水下地形测量技术的分析与应用

摘要

介绍了GPS无验潮多波束水下地形测量的基本原理及方法要点.以琼州海峡跨海通道工程水下地形测量为例,对GPS潮位修正及多波束水深测量结果进行了分析.结果表明,综合运用GPS RTK和多波束测深技术进行宽水域水下地形测绘,可有效提高测量精度和工作效率.%The principle and methodology of GPS assisted multi-beam sonar in underwater topographic without tidal observation was introduce in this paper. Taking the underwater topography data collected at Qiongzhou Strait for example, we analyzed the amendment of the GPS tidal observation and results of Multi-beam underwater topography. The results show that the integrated use of GPS RTK and multi-beam sonar technology in the underwater topographic of wide waters, which can effectively improve the measurement accuracy and efficiency.
