| Abstract: | The principle and methodology of GPS assisted multibeam 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. |
