基于RTK实时定位的水深测量精度检验方法研究

Research on Accuracy Inspection Method of Real-time Positioning Water Depth Survey Based on RTK

在水深测量检验过程中,对水下地形精度进行检验时,测区周边验潮站布设困难或水位观测效率低且造成人力物力的消耗,采用验潮模式开展水深测量检验存在一定困难。本文结合实际检验工作,有针对性地开展水深测量精度检验,分别对无验潮模式水深测量检验与验潮模式下水深测量精度检验方法进行验证,并对结果进行分析。分析表明:基于RTK实时定位无验潮模式水深测量检验与验潮模式下水深测量检验结果一致,可用于水下测量成果质检。

In the process of accuracy inspection of bathymetric survey,it is difficult to set up tide gauge stations around the survey area or the water level observation efficiency is low,which results in the consumption of manpower and material resources,it is difficult to carry out bathymetric survey with tide gauge model.In this paper,the accuracy inspection of water depth measurement is carried out in accordance with the actual inspection work,and the verification methods for water depth measurement without tide gauge mode and for water depth measurement under tide gauge mode are carried out respectively.The analysis shows that the result of real-time positioning based on RTK under non-tide gauge mode is consistent with that of water depth survey under tide gauge mode and can be used for the quality inspection of underwater survey results.
