The AIS receives and processes the data transmitted from all equipped vessels in VHF radio range and automatically transmits "own ship" information to other vessels and shore stations. The information gathered by the AIS was presented on the FA 100's LCD screen and can also be displayed on a vessel's radar/chart plotter screen. The initial display shows the relative bearing and distance of all in-range AIS-equipped vessels. Positioning the cursor on a selected target discloses the "other" vessel's name, MMSI (Maritime Mobile Service Identity), course, position, speed, velocity vector, classification (type of vessel), maneuvering information, closest point of approach (CPA) and time to closest point of approach (TCPA). The "other vessels" data will also include type of vessel, length, breadth, draft, destination and whether it is carrying hazardous cargo. Connecting the AIS to the radar changes previously unspecific targets on the screen to uniquely identified vessels. Your radio call to "ship on my port bow at three miles" can now be done with either a voice call using the vessel's name or a DSC call using the vessel's MMSI. Connecting the AIS to a computer allows you to exchange short, safety-related E-mail messages between vessels. Although the detailed exchange of navigation data might not be critical in the open sea, its value when under way in a busy, fog-shrouded harbor can be inestimable.
