基于CORS-RTK无验潮的海上光伏水深测量精度分析
Analysis on the Accuracy of Sea Photovoltaic Bathymetric Survey based on CORS-RTK without Tide Guage
摘要
Abstract
The development and construction of offshore photovoltaic project is a complex project with great challenges and difficulties.High-precision surveying of seabed topography and landforms is crucial to the smooth development of offshore photovoltaic projects.Tradi-tional surveying methods require the deployment of tide gauges in advance to obtain tide data,but there are great difficulties in deploying tide gauges in areas without docks,and manual tide gauge also have safety risks.In response to this problem,the CORS-RTK-based depth surveying method without tide gauges has gradually been applied to underwater topography surveying because it does not require the deployment of tide gauges and has the advantages of being fast and efficient.However,compared with traditional surveying methods,it is still unclear whether it can meet the accuracy requirements of seabed topography surveying.Therefore,combined with actual engineering cases,the single beam inspection data is used as the inspection standard to compare and analyze the data accuracy of the depth surveying mode without tide gauge and the conventional tide gauge operation mode.The results show that the depth surveying data errors of CORS-RTK without tide gauge mode and conventional operation mode both meet the requirements of the"Specification for Marine Engineering Topographic Surveying",and the data stability and accuracy difference between the conventional operation mode and CORS-RTK without tide gauge mode is small;the conventional operation mode is time-consuming,costly,and inefficient,while CORS-RTK without tide gauge mode can not only improve operational efficiency and save costs,but also simplify the later data processing,and the CORS-RTK technology has strong climate adaptability,enabling it to implement surveying in bad weather or poor sea conditions;when the surveying time is tight,the climatic conditions are bad,and the traditional tide gauge method is difficult to implement,the CORS-RTK without tide gauge mode can be used for underwater surveying.The study results can provide reference for marine underwater topography surveying.关键词
