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 ...

The classical DGNSS technique is an enhancement to a primary GNSS system that consists of the determination of the GNSS position for an accurately-surveyed position known as reference station. DGNSS accuracy is in the order of 1 m (1 sigma) for users in the range of few tens of km from the reference station.

Among the different GNSS Augmentation systems, the DGNSS system were the first ones to be developed and now are widely used by navigation users. Nowadays, almost all commercial GPS units, even hand-held units, offer DGPS data inputs. To some degree, a form of DGPS is now a natural part of most GPS operations. [1]

In ITU-R M.823-3, on the technical characteristics of differential transmissions for Global Navigation Satellite Systems (GNSS), IALA was assigned the task of coordinating the allocation of identification (ID) numbers to radio beacon transmitting stations and reference stations.

More information on marine radiobeacon DGPS and Differential Global Navigation Satellite Systems (DGNSS) can be found in IALA Recommendation R‐121 and Guideline 1112. …

Learn what Differential GNSS (DGNSS) is and how it resolves positioning errors and supports post-processing solutions.

Differential global navigation satellite system (differential GNSS; abbreviated DGNSS) is a technique for reducing the error in GPS-derived positions by using additional data from a reference GNSS receiver at a known position.
