I have a memo / stakeholder briefing document from the General
Lighthouse Authorities UK/Ireland (can't see any confidentiality notes
on it), that states:

""
4. Effect if France Terminates eLoran
It is hoped that the RNTF [http://rntfnd.org] commercial initiative
can maintain the continuity of eLoran transmissions from France beyond
the end of 2015. However, in the event that the French and Norwegian
transmissions were to cease, all maritime eLoran Navigation capability
in UK waters would be lost immediately. In addition, the UTC basis of
precise Timing of the Anthorn eLoran transmissions would also be lost,
unless an alternative link to a source of UTC in the UK could be
provided. The Loran transmissions from Anthorn could be continued to
provide precise Timing (with intervention to synchronise transmissions
to UTC) for the benefit of UK and Irish CNI, but the maritime mandate
of the GLA does not cover this intervention. Without French
transmissions and hence with no maritime benefit, the GLA have no
mandate to maintain any eLoran capability in the UK and would plan to
close the service down.
""

Chronos in the UK have partnered with UrsaNAV to form this:
http://taviga.com . The various UK government bodies support eLORAN
and the people involved say they have the capacity to make Anthorn a
master station. They need a UTC reference, but given that the NPL are
transmitting MSF from Anthorn, I would assume that traceable UTC is
already there. All that's left to do is wait to see what actually
comes out of this, but things are looking bleak for now; for
positioning you can't do much with Anthorn alone.

Thanks,
Wojciech
