Differential GPS

Differential GPS (DGPS) enhances the accuracy of standard GPS by using a network of fixed ground stations. These stations know their precise locations and can detect errors in the GPS signals received from satellites. By comparing their known positions to the GPS data, they calculate corrections and send these adjustments to nearby GPS receivers. This process significantly improves the location accuracy from about 10 meters to within 1 meter. DGPS is widely used in applications requiring high precision, such as surveying, navigation for ships, and agricultural equipment guidance.

    Differential GPS (DGPS) enhances the accuracy of standard GPS by using a network of fixed ground-based reference stations. These stations know their exact position and can detect any errors in GPS signals caused by atmospheric conditions or satellite inaccuracies. They then broadcast correction signals to nearby GPS receivers. As a result, DGPS can improve location accuracy to within a few meters, compared to the typical 10 to 15 meters for standard GPS. This technology is widely used in applications requiring precise positioning, such as marine navigation, agriculture, and surveying.
