UrsaNav has teamed with industry leading partners, including Nautel and Symmetricom, to provide comprehensive eLoran solutions for service providers and users. Visit for additional information.  
On February 7, 2008, the United States Department of Homeland Security announced that eLoran is adopted as the national backup system to GPS for position, navigation, and timing. Click here for the Press Release

Apparently, that "announcement" was not followed up by action to deploy eLoran in the U.S.

Since that release, the ILA has been "encouraging" the DHS to follow up the promise of deployment and operation of eLoran as a GPS alternative nav system. Our cause  was joined by the National Position, Navigation and Timing Advisory Board.
