Symbol Description
AIS scaled target. The symbol is scaled according to
physical size of the vessel as obtained from AIS info,
if available.
AIS moving target with predicted course extension
(dashed line). Will show as a straight line if going
straight or if no rate-of-turn AIS data is available.
AIS moving target with trail.
AIS moving target with predicted turn extension
(based on rate-of-turn AIS data.)
AIS moving target with predicted turn extension
(based on rate-of-turn AIS data) and turn trail.
Associated target. When the radar and the AIS signal
acquire the same target, the system will display the
target with one symbol. This reduces the number of
AIS symbols and radar targets on the PPI. The
association function also compensates for a possible
failure in one of the two targets, e.g., if the radar
target is positioned behind an island, the system
keeps tracking and visualizing the AIS target.
Ú Note:
AIS | GO XSE/XSR Operator Manual
The radar target continues to be analyzed
by the system when the target association is
active.
