Dgps stations
WebDGPS stations transmit the difference between positions indicated by GPS satellite systems and the known fixed position of the station. This allows higher accuracy. DGPS transmissions are 100 or 200 baud and are transmitted on frequencies from 285 kHz to 325 kHz. Hundreds of these stations are operated by the Coast Guard and other agencies, … WebTableau des stations de référence du DGPS au Canada Position géographique Nom de la station Nos d’ident. des stations de référence Latitude DGPS Ident. station Longitude Fréquence [kHz] Bit/s Cape Race, T.-N. 338,339 940 46 46 N 53 11 W 315 200 Cape Ray, T.-N. 340,341 942 47 38 N 59 14 W 288 200
