Differential GNSS Real Time Positioning Service



    The SatRef system produces the Differential GNSS (DGNSS) correctional data stream round the clock to the users by means of the SatRef NTRIP server. Users can obtain the DGNSS correctional data stream via the internet. The real-time positional accuracy of DGNSS is about 1-2 m. It could be used in navigation (land and sea), fleet management, location based services and mobile GIS systems.
