Differential Global Positioning System (DGPS)

Differential Global Positioning System (DGPS) enhances the accuracy of standard GPS by using ground-based reference stations. These stations compare their known position to the GPS data they receive, detecting any errors. They then send correction signals to nearby GPS receivers, improving location accuracy to within a few centimeters instead of meters. This technology is commonly used in applications that require precise positioning, such as surveying, navigation for ships and aircraft, and agricultural systems. DGPS significantly improves the reliability of location information, making it invaluable for both commercial and recreational purposes.
