The Type 1 or Type 3 AIS solutions can be configured to a range of Sealite products, including ocean buoys, solar marine lanterns, and stand-alone models. 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 users. 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. Sealite's AIS AtoNs can be delivered pre-programmed or can be provided with software enabling the user to program the unit Low Power Consumption Sealite’s AIS solutions have an incredibly low power consumption of less than 0.5 Ah/day making them suitable for a large range of solar installations. The compact AIS AtoN Transponder is available installed within Sealite’s range of self-contained lantern assemblies - providing installation flexibility and operational reliability for a range of environmental conditions and demanding duty cycles. Synthetic & Virtual AIS AtoNs Sealite's AIS AtoNs are able to support real, synthetic and virtual transmissions. Versions of the selfcontained AIS Transponder are available without the lantern integration to enable the benefits of AIS if a visual navaid is not required. Type 1 & Type 3 AIS AtoNs AIS AtoNs use either the FATDMA (Fixed Access Time Division Multiple Access) or RATDMA (Random Access Time Division Multiple Access). Type 1 AIS AtoN uses the FATDMA access scheme and can only transit AIS signals. This means the AtoN requires a nearby base station to reserve the slots (message spaces) used by the AIS enabled AtoN. Type 3 AIS AtoN has the capability to transmit as well as receive and uses the RATDMA access scheme. This allows the AtoN to autonomously allocate slots for its own transmission by listening to AIS frequencies and determining which slots are available for use. The Type 3 AIS AtoN is able to be installed at any location because, unlike Type 1 AIS, it does not require slots to be reserved and can therefore be used in areas with or without a base station. Sealite’s Type 3 AIS is able to ‘chain’ several units together to extend the transmission range. The Type 3 AIS AtoN can also support remote control functions including lantern flash character, ON/

Integrated Internal AIS The SL-155 lanterns are available with a class-leading integrated,low-powered Type 1 or Type 3 AIS. When fitted, the AIS is encapsulated within the body of the SL-155 to maintain the weatherproof integrity and come standard with GPS. All 3 models can also be ordered with an external Type 1 or Type 3 AIS transponder if required, along with various solar power options. Note: 2.5 degree model available with external antenna only.
