Marine Aids to Navigation Strategy

The three General Lighthouse Authorities (GLAs) - Trinity House Lighthouse Service (THLS), the Northern Lighthouse Board (NLB) and Commissioners of Irish Lights (CIL), provide marine Aids to Navigation (AtoN) to the mariner in the interests of general navigation.

The GLAs have a shared mission statement:

"To deliver a reliable, efficient and cost effective AtoN service for the benefit and safety of all mariners."
