General Lighthouse Authorities eLoran Transmissions

The Northern Lighthouse Board, Trinity House and the Commissioners of Irish Lights began transmissions of eLoran from a radio site operated by VT Communications at Anthorn, Cumbria in January 2008.

The eLoran transmittions will enable the GLAs to develop an eLoran system in the UK and Ireland, for use as a complementary system to the Global Navigation Satellite System (GNSS). eLoran is dissimilar to GNSS in many respects, relying on low frequency transmissions from transmitters on the ground. Because of its different characteristics it can provide an effective backup and complement to GNSS.

Loran-C uses low frequency terrestrial transmissions and provides another source of navigation information should satellite navigation systems be unavailable. The transmissions are integrated with those of other transmitters in Europe.

Users of the system are encouraged to provide feedback on any aspect of the system by contacting the relevant GLA Monitoring Centre:-
