一种基于GPS与姿态仪的航道测深技术

Multi-beam Sounding Technique Combining with GPS and Attitude Indicator

介绍了典型的多波束测深系统组成,以及SONIC 2024型多波束测深仪、VS110型GPS及MRU-5型姿态仪性能与特点。提出了GPS与姿态仪优化配合的思路,通过对比研究GPS与姿态仪各自独立工作、GPS仅向姿态仪提供速度数据以及GPS同时向姿态仪提供速度与方向数据3种情况下对航道测深结果的影响,得出了GPS同时向姿态仪提供速度与方向数据可提升水深测量精度的结论。通过在天津市临港经济区三期14区围堤及部分吹填工程的应用,证明了该优化方案的实用性与有效性。

This paper introduces the typical multi-beam system composition,and SONIC type 2024 multibeam echo sounder,VS110 GPS and MRU-5 attitude indicator and performance characteristics. Compared the study VS110 type GPS and MRU-5 type attitude indicator to work independently,only provides speed( vacations) data,and provide speed( vacations) and direction( HDT) data at the same time in water depth measurement,it was found that providing the speed( vacations) and direction( HDT) data the same time can promote the conclusion of water depth measurement precision.Through the engineering application in Tianjin area of 14 cofferdam and part of land reclamation,the practicability and effectiveness of the optimization scheme was proved.
