11. AIS OPERATIONS
With connection of an AIS transponder, up to 100 AIS targets (ship’s name, position,
navigation data) can be shown on the plotter display. The AIS operation requires
WGS-84 geodetic datum.
Note:
Set the datum for the port connected an AIS transponder to WGS-84
(section 9.6.1). It is dangerous to select the other datum because the position of an
AIS target can not be displayed correctly.
