Overview of DGPS Maintenance

DGPS system is operated by National Maritime PNT Office of the Ministry of Ministry of Oceans and Fisheries.
This system generates corrected information after observing GPS error factors collected by the standard stations distributed
nationwide and broadcasts this information to users. This is used in various areas such as navigation system, traffic management,
disaster management, geography, surveying, agriculture, and forestry. Maintenance service is provided so that such crucial
positioning systems over the country can continue to provide positioning information 24 hours a day without stopping.
