Differential Gps (Dgps) (Boating)

A highly accurate global positioning system (GPS) that utilizes a differential radio beacon and receiver to compute and correct the error of all visible satellites sending data to a conventional GPS unit.

Differential Gps (Dgps) (GPS)

A technique to improve GPS accuracy that uses pseudo-range errors measured at a known Base Station location to improve the measurements made by other GPS receivers within the same general geographic area. It may be implemented in real-time through the provision of a communication link between the GPS receivers, transmitting the correction information in the industry-standard RTCM format, or various proprietary formats. May be implemented in single Base Station mode, in the so-called Local Area DGPS (LADGPS), or using a network of Base Stations, as in the Wide Area DGPS (WADGPS) implementation.
