Coast Guard will terminate Long Range Aids to Navigation (Loran-C) signal February 8

ALAMEDA, Calif. — The U.S. Coast Guard will cease broadcasting the North American LORAN-C signal Feb. 8.

As a result of technological advancements during the last 20 years and the emergence of the U.S. Global Positioning System, LORAN-C is no longer required by the armed forces, the transportation sector or the nation's security interests, and is used by only a small segment of the population.

LORAN-C was originally developed to provide radio navigation service for U.S. coastal waters and was later expanded to include complete coverage of the continental U.S. as well as most of Alaska. Coast Guard men and women have done an excellent job running and maintaining the LORAN-C signal for 52 years. It is a service and mission of which the entire Coast Guard can be proud.
