Differential GPS (DGPS) is a kind of GNSS Augmentation system based on an enhancement to primary GPS constellation information by the use of a network of ground-based reference stations which enable the broadcasting of differential information to the user – also named rover – to improve the accuracy of his position – the integrity is not assured.
The Differential GNSS techniques and systems are explained in detail in the articles:
The case of DGPS is the same as DGNSS but using only measurements from the GPS constellation.
The DGPS term can also refer to specific implementations using DGNSS technique. It is often used to refer specifically to systems that re-broadcast the corrections from ground-based short-range transmitters, such as it occurs in maritime domain. Examples of DGPS systems are explained hereafter.
