AIS = Automatic Identification System (for ships)
The AIS system has also been refereed to as a poor mans RADAR. With a more modern chart plotter the crew aboard a vessel can view a representative image on an plotter in relation to the vessel that they are currently crewing. Therefore potential collision scenarios can be calculated by the electronics and also viewed by the navigator to determine what courses of action are appropriate.
They are two types of systems A and B. (Simplistically stated below))
Type A is for commercial boats and uses higher transmit power and sends its signal more frequently depending upon ship 's speed..
Type B is for non commercial boats and uses a lower transmit power and transmits a signal in terms of minutes.
A license is required to transmit a signal and transmitters must be registered.
