Differential GPS (DGPS)

DGPS enhances the accuracy of GPS by using ground-based reference stations to correct satellite signals. It improves positioning accuracy to within a few centimeters, crucial for precision navigation and operations like dredging. DGPS is widely used in coastal and harbor navigation. Technological advancements continue to improve its reliability and integration with other systems. Regulatory standards ensure consistent performance. Training in DGPS operation and interpretation is essential for maximizing its benefits. DGPS represents a significant advancement in maritime navigation, offering enhanced precision and safety.
