Differential Global Navigation System (DGNSS) means a form of GNSS in which the reliability and accuracy are enhanced by broadcasting a time varying correction message from a GPS monitoring receiver (differential mode) at a known position onshore. If available, the corrections are fed automatically into the GPS receiver on board and used to compute an improved position.
