WebNautical charts and GPS/DGPS. DGPS Stations. The Differential Global Positioning System (DGPS) service transmits correction signals to GPS navigation equipment on board vessels. The DGPS service improves the accuracy of your GPS position and the quality of the signal. The DGPS service consists of 12 DGPS stations on the Norwegian coast. http://help.t4d.trimble.com/documentation/manual/version5.0/server/NMEARecv_GEN_GGA_Description.htm

DGPS also uses ground or fixed GPS stations to determine the location, but differs in that it finds the difference … Differential Global Positioning Systems (DGPSs) supplement and enhance the positional data available from global navigation satellite systems (GNSSs). A DGPS for GPS can increase accuracy by about a thousandfold, from approximately 15 metres (49 ft) to 1–3 centimetres (1⁄2–1+1⁄4 in). DGPSs consist of … See more When GPS was first being put into service, the US military was concerned about the possibility of enemy forces using the globally available GPS signals to guide their own weapon systems.
