AIS target display
AIS TARGET DISPLAY
The AIS Target symbol is a blue triangle with a speed vector (dotted line) and the COG vector
(continuous line). The speed vector length depends on the speed of the target (true vector) or
on both own ship and target speed (relative vector). Keep in mind that according to
standards the AIS target must display the ship scaled icon.
True vector Relative vector
When a target is lost, the vector is no longer displayed and a small line crossing the green
triangle shows the status of the target in the table. On the chart the blinking red cross
appears over the AIS symbol indicating the lost target .
When the set CPA/TCPA alarms are activated the icon blinks.
NOTE
If the Rate of Turn (ROT) is received for a specific target, a small bar is displayed at
the end of the target vector indicating the direction of the turn.
