基于组合定位技术的多波束海洋地形测量分析

Multi-beam Marine Topographic Survey Analysis Basedon Combined Positioning Technology

目前,陆地资源开发已接近于饱和状态,海洋资源的重要性日益凸显。常见的海洋地形测绘方法以GNSS导航定位与水声探测设备相结合为主,但在使用GNSS导航定位技术完成水下地形测绘任务的过程中,部分远海区域的观测信号质量不佳,定位精准度不足。为进一步提升定位精度,将GNSS技术与INS技术相结合,配合多波束水深测量技术,完成目标海域的地形测绘,得到更加精准的测区三维地图,以保证水下地形的测绘精度达到理想水平。

At present,the development of land resources is close to saturation,and the importance of marine resources is becoming increasingly prominent.Common marine terrain surveying and mapping methods are mainly combined with GNSS navigation and positioning and underwater acoustic detection equipment.However,in the utilization process of GNSS navigation and positioning technology to complete underwater terrain surveying and mapping tasks,the observation signal quality in some far-sea areas is poor,and the positioning accuracy is insufficient.In order to further improve the accuracy of positioning,GNSS technology and INS technology are combined with multi-beam bathymetric measurement technology to complete the topographic mapping of the target sea area and obtain a more accurate three-dimensional map of the survey area,and to ensure that the surveying accuracy of the underwater terrain reaches at an ideal level.
