MFAIS circuits are AIS AtoN devices integrated inside our LED lanterns. The AIS AtoN transponder provides automatic information on the GPS position of the marine aid to navigation (AtoN); thus making easy the location and identification of buoys, beacons, and lighthouses on a vessel or an AIS Base Station chart. Thanks to its minimum energy consumption, those circuits can be integrated with our self-powered lanterns. Its modular construction allows its installation subsequently to the purchase of an MSM lantern. MFAIS complies with IMO, IEC, ITU, and IALA Standards.
