The MTA unit is an AIS AtoN transponder device housed in a IP 67 watertight box, providing 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.

This unit is designed to be connected to any beacon of the market with a serial port and NMEA 0183 protocol, thus transmitting operating status data.

Thanks to its minimum energy consumption, those devices can be integrated in buoys and on-shore lanterns.

The MTA unit complies with IMO, IEC, ITU and IALA Standards.
