Sealite’s AIS (Automatic Identification System) enabled AtoNs operate on the international VHF Maritime Mobile Band, enabling Port Authorities and other users to remotely monitor the real-time status of their AtoN installations.

Mariners in the broadcasting region are provided with crucial Message 21 information (as defined by the International Telecommunications Union (ITU) such as AtoN operational status and positioning – revolutionising the VTS system by expanding AtoN information availability to mariners worldwide.

The compact AIS AtoN TeleBeacon is available installed within Sealite’s range of SL125/C Type 2 Complete Lantern Assemblies, as well as the compact SLC600 Solar Marine Lantern, providing installation flexibility and operational reliability for a range of environmental conditions and demanding duty cycles.

Versions of the self-contained TeleBeacon are available without the lantern integration to enable the benefits of AIS if a visual navaid is not required.

The TeleBeacon interacts with most AIS enabled charts or radar screens, both at sea and ashore, broadcasting imperative information at regular intervals about the type and name of the AtoN, as well as GPS position. With these capabilities, Sealite’s AIS enabled AtoNs add a new information quality to VTS systems.

In addition, the AIS enabled AtoN broadcasts AIS Message 6 received by the designated base station, allowing the operator to monitor the AtoN for solar and battery voltage, flash code setting and light status. Meteorological and hydrological data and a host of other parameters can be fitted.

This fixed frequency telemetry unit operates on the designated AIS1 and AIS2 channels.

Sealite’s AIS enabled AtoNs were developed in technology partnership with Maritec Ltd and in accordance with the International Association of Lighthouse Authorities (IALA) Recommendations, and ITU Publications – creating completely integrated, self-contained, AIS enabled AtoNs.
