A form of GPS in which the reliability and accuracy are enhanced by broadcasting a time-varying correction message from a GPS monitoring receiver (Differential Mode) at a a known position on shore. The corrections are fed automatically to the GPS receiver on board and used to compute an improved position.
Differential Global Positioning System. A positioning procedure that uses two receivers, a rover at an unknown location and a base station at a known, fixed location. The base station computes corrections based on the differences between its actual and observed ranges to the satellites being tracked.
Differential GPS - A method of improving GPS accuracy using measurements at a known location to improve the measurements made by other GPS receivers within the same general area.
Differential positioning - DGPSA technique used to improve positioning or navigation accuracy by determining the positioning error at a known location and subsequently incorporating a corrective factor (by real-time transmission of corrections or by postprocessing) into the position calculations of another receiver operating in the same area and simultaneously tracking the same satellites.
Differential Global Positioning System. is a technique used to improve GPS accuracy. See differential correction.
ifferential GPS can be used when you have two receivers not too far from each other. The errors due to the satellite clock, the satellite orbit, the ionosphere, the troposphere and SA affect both receivers in the same way and with the same magnitude. If we know the exact location of one receiver, we could use that information to calculate errors in the measurement and then report these errors (or correction values) to the other receiver, so that it can compensate for them.
ifferential GPS. An extension of the GPS system that uses land-based radio beacons to transmit position corrections to GPS receivers. DGPS reduces the effect of selective availability, propagation delay, etc. and can improve position accuracy to better than 1 meter.

Differential Global Positioning System. Satellite-based navigation aid for precise measurement of location. When the bottom is out of range or moving, calculating the distance between DGPS position fixes and dividing by the time between those fixes can be used to measure the platform velocity.
differential global positioning system. a method of using GPS which attains the position accuracy needed for precision farming through differential correction.
Differential Global Positioning System or Dynamic Global Positioning System
Differential GPS, the use of GPS measurements that are differentially corrected
Differential Global Positioning System. Method of using GPS that improves the position accuracy through differential correction.
GPS users can get improved accuracy with Differential GPS (DGPS), which corrects GPS signals to within an average of three to five meters (as compared to a typical 6-12 meters with the normal GPS signal). This system consists of a network of towers that receive GPS signals, and then transmit a corrected signal via beacon transmitters. In order to get the DGPS corrected signal, users must have a differential beacon receiver and beacon antenna in addition to their GPS.
