【Abstract】 This paper studies the feasibility of using satellite station difference technology to carry out the production and detection of 3D non tidal bathymetric survey in the offshore waters of Shanghai. In the offshore waters of Shanghai, the satellite station difference technology and tidal observation, RTK method are used to complete the bathymetric comparison test and data result analysis. The satellite station difference technology and bathymetric instrument are used to coordinate the bathymetric data collection, and the sea level elevation is converted from the refined model of the sea quasi-geoid, it is applicable to the production and detection of 3D non tidal bathymetric survey.更多还原
