Abstract
An ocean current measurement method, includes: acquiring three-dimensional coordinates measured by four GNSS (Global Navigation Satellite System) positioning modules on the surface drifting buoy and attitude data of the surface drifting buoy measured by an attitude sensor; correcting the three-dimensional coordinates measured by the four GNSS positioning modules based on the attitude data; optimizing the corrected three-dimensional coordinates of the four GNSS positioning modules according to the mounting positions; converting the optimized three-dimensional coordinates of the four GNSS positioning modules into latitude and longitude coordinates; and calculating coordinates of the surface drifting buoy, an instantaneous flow velocity and flow direction of ocean current and sea surface elevation through the latitude and longitude coordinates of the four GNSS positioning modules. The coordinates with higher precision can be obtained, and the flow velocity, flow direction and sea surface elevation of the sea area where the buoy is located can be measured.
