UK opts for eLoran as backup
Jul 26 2013
The UK is to install seven eLoran stations along to East and South coasts of
the UK, following approval be the Department of Transport
This will counter the threat of GPS jamming.
The stations will provide alternative position, navigation and timing (PNT)
information to ensure that ships equipped with eLoran receivers can navigate
safely in the event of GPS failure in one of the busiest shipping regions in
the world.
The UK claimed to be the first in the world to deploy this technology for
shipping companies.
The rollout, led by the General Lighthouse Authorities (GLAs) of the UK and
Ireland, will replace the equipment in two prototype stations at Dover and
Harwich and five new stations will be deployed in the Medway, Humber,
Middlesbrough, Firth of Forth, and Aberdeen.
The GLAs have contracted UrsaNav to deploy and deliver initial operational
capability by the Summer of 2014.
Several countries worldwide are consulting with the GLAs to benefit from their
knowledge and experience of eLoran and other resilient PNT technologies.
South Korea, for example, has said that it wants to establish an eLoran
alliance with the UK while it pursues its own rollout of differential eLoran
stations, due for completion in 2015. Last year, South Korea was the victim of
a 16-day GPS jamming attack by North Korea.
Today, many devices and applications rely on GPS-based information, including
telecommunications, smart grids and high frequency trading.
It also plays a fundamental role in delivering the PNT data that ships rely on
to ensure safe navigation. GPS signals are vulnerable to both deliberate and
accidental jamming, which is causing increasing concern because of the wide
availability of GPS jammers online for as little as £30 capable of causing
complete outages across all receivers currently on the market.
Martin Bransby, research & radionavigation manager at the GLAs, said, "Demands
on marine navigation continue to increase and awareness of the vulnerability of
GPS is growing, yet electronic systems at sea have not evolved at a sufficient
pace to meet these challenges.
"Today's announcement is a significant step towards improving safety at sea,
but few vessels currently have receivers to take advantage of the new stations.
We hope that the maritime industry will respond proactively to the new stations
rollout by installing eLoran receivers on more vessels," he said.
Commenting on the announcement, Stephen Hammond, UK Minister for Shipping,
said: "The deployment of seven eLoran stations follows the successful
demonstration of eLoran as a resilient PNT technology and puts the UK at the
forefront of developments to improve navigational safety. I applaud the General
Lighthouse Authorities on this initiative and am keen to see how it benefits
mariners when in use up and down the country."
Charles Schue, president and CEO of UrsaNav, said, "We are very proud to be
working with the General Lighthouse Authorities on this project, which is the
most advanced of its kind in the world. The number of enquiries we receive
about eLoran and other resilient PNT technology continues to increase and we
are now approached for further information on a daily basis. Much of this is
testament to the example being set in the UK, raising awareness of the need for
a robust backup to GPS."
ELoran technology is based on longwave radio signals and is independent and
complementary to GPS. The GLAs carried out the world's first successful
demonstration of a prototype automatic resilient PNT system using eLoran, in
trials completed on board the `THV Galatea' out of Harwich on several trips
between 28th February and 1st March this year.
Full operational capability covering all major ports is expected by 2019.
