The General Lighthouse
Authorities award a 15-year eLoran contract
to VT Communications
Published:
- May 2007
The General Lighthouse Authorities (GLAs)
has announced the award of a prestigious
fifteen-year contract to VT Communications
(part of VT Group plc) for the provision of
a state-of-the-art enhanced Loran (eLoran)
radionavigation service to improve the
safety of mariners in the UK and Ireland.
The first development phase of this
contract, until 2010, will build on existing
successes and provide a focus for a European
agreement on eLoran service provision. This
would then trigger the start of the
operational phase from 2010 onwards.
The Department for Transport is sharing the
costs during the development phase having
recognised the broader potential of Loran to
improve the resilience of critical transport
infrastructure.
eLoran is intended to assist mariners
navigating the complex and crowded waters
around our shores and those of our northern
European neighbours. It complements Global
Navigation Satellite Systems (GNSS) such as
GPS and is entirely independent, allowing
users to retain the benefits of electronic
positioning, navigation and timing when
satellite signals are disrupted.
This contract will see VT Communications
develop a new Loran station at its radio
communications facility in Cumbria, UK. The
first signals from the Cumbrian eLoran
station will be transmitted on 1st October
2007 with a full trial service launched in
November 2007. The existing trial service
will be suspended by the end of July 2007.
VT Communications Managing Director, Doug
Umbers says: VT Communications is proud to
be working with the GLAs to deliver this
critical service to their user community.
This contract demonstrates VT Communications
unrivalled expertise in delivery of the LF
infrastructure and service provision
projects, providing the GLAs with a
radically improved service.
We chose VT Communications because of its
commitment to service provision and its
flexible approach to partnership , comments
Dr Sally Basker, the GLAs Director of
Research and Radionavigation.
Over the last decade we have worked hard to
reduce the overall cost of service provision
by 50% in real terms. e-Navigation is the
maritime sector s future: berth-to-berth
navigation in the digital world with its
associated safety, security, environmental
and economic benefits. As we press ahead
with e-Navigation, eLoran provides the only
way of maintaining our service levels until
2020 without undue increases in cost or
risk. eLoran will help us to deliver a
reliable, efficient and cost-effective Aids
to Navigation service for the benefit and
safety of all mariners.
