DGPS
DGPS (Differential Global Positioning System) data is mainly transmitted in the low frequency band e.g.
285 - 315 kHz. It is a correction signal for GPS receivers, and is used to increase the accuracy of the sat-
ellite-based GPS signal. DGPS is based on the transmission of correction data by a reference station, the
position of which has been determined with high accuracy by traditional position-finding measurements.
With the correction data, an absolute accuracy to within 4 meters can be achieved.
