UK rolls out GPS back-up eLoran

The UK General Lighthouse Authorities (GLA) have announced that they have
installed a system called eLoran in seven ports across Britain.
The GLA say many critical instruments on ships use Global Navigation
Satellite Systems, and if they fail the consequences could be disastrous.
The new system, which is ground rather than satellite-based, is designed to
be used in the event of a GPS failure.Until now, there has been no "Plan B"
if GPS goes wrong, but the GLA says eLoran will be an important tool.The
technology was developed during World War Two.
The Long Range Navigation system (Loran) was the brainchild of US
scientists and was used to guide US Navy warships as battles raged in the
Pacific.After the war ended, it was updated and renamed Loran-C, and
adopted by mariners around the world - until GPS took over.
Now though, rebranded as eLoran, its infrastructure has been upgraded to
make it more accurate and it is making a comeback.
While GPS transmitters are based in space, eLoran's are based on the ground.
The General Lighthouse Authorities have finished installing eLoran in seven
ports along the east coast of Britain, completing the first phase of their
roll out. It is now in place in Dover, Sheerness, Harwich and Felixstowe,
Middleborough, Leith, Humber and Aberdeen.
For now, eLoran is being tested for shipping, but it could also play a role
on land for the vast array of systems that use GPS.
The US Coast Guard is busy decommissioning the existing eLoran
infrastructure. And in Europe, the governments of Norway and France have
said they will cease operations next year.
GPS jammers are available online from as little as £30, and resilience to
such attacks is essential for the safety and security of shipping and
trade. Ships that are fitted with eLoran receivers will automatically
switch to the system when GPS signals are lost, receiving position,
navigation and timing (PNT) information which will allow them to proceed
safely.
The UK is the first in the world to deploy this technology for shipping
companies operating both passenger and cargo services, with rollout
initially approved by the UK Department of Transport in 2013. Full
operational capability covering all major UK ports is expected by 2019.
