Differential GNSS (DGNSS) is a kind of GNSS Augmentation system based on an enhancement to primary GNSS constellation(s) 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.
There are several DGNSS techniques, such as the classical DGNSS (or DGPS), the Real Time Kinematic (RTK) and the Wide Area RTK (WARTK).
