The offshore buoy RTK positioning system consists of an online NRTK service, a marine waterproof RTK positioning module, a high-precision maritime antenna, a long-range data transmission unit and a buoy data processing system. The base station supplies real-time differential correction data to compensate for marine positioning errors. The buoy module continuously obtains centimeter-level positioning data under complex marine conditions. It enables real-time marine monitoring, hydrological data calibration and dynamic observation of offshore waters.
