DGNSS (Differential Global Navigation Satellite System)

DGNSS (Differential Global Navigation Satellite System) improves the accuracy of positioning obtained from GPS and other satellite navigation systems. It uses a network of ground-based reference stations with precisely known locations that monitor satellite signals. These stations detect errors such as atmospheric disturbances or satellite clock issues and send correction data to users. By applying these corrections, DGNSS significantly enhances the precision of position data—often to within a meter—making it ideal for applications like navigation, surveying, and precision farming. It essentially acts as a real-time quality control system that ensures more reliable and accurate positioning information.
