"The U.S. Coast Guard's Director of Prevention Policy announced publication in the Federal Register of plans to 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."
The inside scoop on the termination of Loran-C is that there IS a backup to GPS that is more accurate than Loran.
I know this because a friend of a friend who has an Aunt that works as a clerk-typist for an officer who used to interface with the Coast Guard and knew a guy that worked on Loran-C in the mid-70's.
All I can add to this is the damned thing better work before the chinamen launch an ionosphere busting nuke and fry the whole GPS schmear to cinders.
