What is FERNS?

FERNS Cooperative Chain

The Far East Radio Navigation Services (FERNS) is a cooperative organization established by three countries, namely South Korea, China, and Russia in line with the formation of an international cooperative chain according to the principle of mutual benefit. FERNS seeks to expand the international cooperative chain's range of usage and promote research and development of radio beacons. It was established on September 7, 1992 through a treaty signed by the Maritime Safety Administration of China, the Korea Maritime and Port Administration of South Korea, and the Navigation Commission of Russia.
