How does it work?
There is an antenna connected to the devices which provides its gps position and call out range. A transponder on the vessel, the icom ma-500tr, recalls this information with AIS ( Automatic Identification System) . It then transmits a more detailed logbook of data, as well receiving. This information includes details of any ship with AIS on the water. If a ship does not have AIS, it will only appear on radar.
The radar is connected to the same network and works through nmea 2000, with the chart plotters. Again for the same positioning reasons, there are three chart plotters on the vessel. The Garmin network of the gps chart plotters, is also connect through nmea 2000 and is compatible and sharing with the icom systems.
This sharing allows the AIS transponder information to appear on the chart plotter screens. It gives you automatic course heading away and to, emergency alarms, and other aids for safety and navigation. That’s how it DSCs it.
These navigation aids are position for the captain and navigator, in the lower helm and on the fly bridge upper helm. This can minimise risks and provide optimum servailance on research, with the delegated crew of three or four.
