Multi-Band Subsea 4G Antenna with GPS, for Offshore Navigation & Seabed Topography Mapping

The GPS system of the deep-sea multi-frequency 4G antenna can provide position, speed and time information for the carrier in any location on land, sea and air in an all-weather, fully automatic, rapid and continuous manner with high accuracy. GPS technology has been widely applied in marine measurement. Carrier phase and differential techniques are used for dynamic water depth measurement, and various scale water depth maps, seabed topography maps and other basic maps are drawn; GPS altimetry data is applied to determine the marine geoid level, etc. At present, various equipment or systems that apply GPS technology to marine measurement are being increasingly put into use, thereby greatly improving the level and efficiency of marine measurement technology.
