Commercial vessels over 300 tons and all passenger vessels are required to have AIS (automatic identification system). This equipment transmits the ships name, MMSI, position, speed, course and heading every few seconds. It enables other vessels and port authorities to get a better picture of what's happening around them - a bit like air traffic control.
The NASA Marine AIS Plotter is the first stand alone AIS receiver / plotter specifically designed for the leisure boat market.
The display provides range selection of 1, 2, 4, 8, 16 and 32 nautical miles. A trail of previous positions clearly shows the relative track of all the targets on the screen.
The unit consists of a dual frequency AIS receiver, demodulator, signal processor, and a backlit matrix display. It receives an NMEA input (RMC) from the boats GPS which puts your boat at the centre of a ‘radar-like’ display. All other AIS carrying vessels are displayed with bearing and range relative to your boat.
Any vessel on the screen can be hightlighted and its data will be displayed on the right of the screen. The data includes the ships name, MMSI number, position, speed, course and heading, distance off, plus latitude and longitude.
In the event that any vessel looks to be at risk of collision with you it can be selected and its data displayed. The MMSI number is immediately available so that in the last resort a DSC call can be made directly to the vessel.
