DGPS

Also, in the area of maritime transport, GMV integrates coastal DGPS corrections transmission systems according to IALA/RTCM standards. These systems rely on transmitter stations set up in diverse coastal points, control centers, and GPS and communications equipment on ships.

Each DGPS Station has 2 reference stations, 2 integrity monitors, a control computer, a communications system (RDSI or GSM), an uninterrupted power supply system and a marine radio beacon. The system has been designed in a redundant configuration, guaranteeing it robustness in the case of failures and creating an autonomous system.

All monitoring and control operations can be performed on site from each one of DGPS stations and remotely from the control centers, from where the differential corrections transmission service parameters and variables can be modified. Furthermore, the system has computer applications that permit the automatic recording of GPS data.
