We are a maritime organisation delivering an essential safety service around the coast of Ireland, protecting the marine environment, supporting the marine industry and coastal communities .We are responsible for providing marine aids to navigation (AtoN) under the Safety of Life at Sea (SOLAS) convention. We provide and maintain over 300 general aids to navigation and we manage about 4,000 local aids to navigation. We also mark or remove dangerous wrecks outside harbour areas around Ireland Our AtoN include radio aids such as Differential GPS (DGPS), Radar Beacons (Racon), and Automatic Identification Systems (AIS), as well as more traditional visual aids such as lighthouses, buoys and beacons. These AtoN complement Global Navigation Satellite Systems (GNSS), such as GPS, which are the primary means of navigation for most mariners. If satellites are not available, these AtoN provide position, spatial awareness, hazard marking and backup
