Trinity House hereby give notice that from 11.00 UTC on 31st December 2015, the General Lighthouse Authorities (GLA) will discontinue the Initial Operational Capability (IOC) prototype/trials of Enhanced LORAN (eLORAN) in the UK and Ireland.

The eLORAN IOC prototype service has been provided by GLA since 31st October 2014. It has used transmissions from Anthorn, UK, operated in cooperation with 8 other transmitters in northwest Europe and augmented by coastal reference receiving stations sited near major ports on the east coast of Scotland and England.

Signals from eLORAN transmitters in France and Norway will go off-air on 31st December 2015. Without these signals, eLORAN in the UK and Ireland will not provide maritime positioning or navigation capability.

Mariners are advised that from 1100 UTC on 31st December 2015 all currently equipped eLORAN and LORAN-C receivers in northwest Europe will cease to function correctly and such receivers should be switched off until further notice.

By Order,
Captain R.H. Barker
