is requested regarding implementation of eLoran in the U.S.
in a Federal Register notice posted on March 22, 2015.
Federal Register Notice Abstract:
"The purpose of this notice is to seek comment from the public and industry
potential plans by the United States Government to implement an
enhanced Long Range
Navigation (eLoran) system as a complementary positioning, navigation,
and timing (PNT)
capability to the Global Positioning System (GPS). The positioning, navigation,
performance of eLoran will vary widely depending on the number of transmitters
and monitor sites for corrections that are implemented.”
Provide a comment on or before May 22, 2015...
Maintenance of safety and security are central requirements
for an alternative system designed to provide positioning, navigation and
timing (PNT) services if satellite-based services are unavailable for any
reason. Additionally, do you think the eLoran system would maintain enough
PNT capabilities for you in the absence of GPS to warrant equipage? Would
the economic impact of a GPS outage be reduced by eLoran for you?

7, 2008, the
United States Department of Homeland
Security (DHS) announced that eLoran is adopted as the national backup system
to GPS for position, navigation, and timing.

That announcement was not followed by action to deploy eLoran in the
Since the 2008 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
Resilient Navigation and Timing
Foundation, and others.
e-Loran continues to be of interest, and is in operation on other parts
of the world.
