WebA Differential Global Positioning System (DGPS) is an enhancement to the Global. Positioning System (GPS) which provides improved location accuracy, in the. range of operations of each system, from the 15-meter nominal GPS accuracy to. about 1-3 cm in case of the best implementations. Webremoved by a technique known as differential GPS (dGPS). dGPS involves placing a stationary GPS receiver at a known position and measuring the supposed range to each satellite. Corrections are then calculated and used by receivers in the nearby area. dGPS can give sub-metre accuracy, but is limited by distance from the reference receiver.
