DGNSS of Korea, South Korea's industrial positioning Leading to the Ministry of Maritime Affairs and Fisheries Satellite Navigation Central Office

Hello and welcome to the website of the National Maritime PNT Office.

The National Maritime PNT Office of the Ministry of Oceans and Fisheries is the one and only domestic operator of a differential global navigation satellite system (DGNSS), which is used to correct the positioning error of GNSS to less than 1m to improve accuracy and to warn satellite malfunctions and failures.

There are 17 DGNSS base and Integrity Monitoring Stations integrated into a nationwide network in order to provide you with accurate positioning information anywhere in the country.

Diverse information and contents are available on our website to help you gain a better understanding of the concept of DGNSS and development of related technologies, and we also answer questions posted on our Q&A message board. We will continue to dedicate our efforts to upgrade our systems and services to provide you with advanced positioning services.

Thank you.
