Heading and Projected Course of Activated AIS Targets
When course over ground and heading information are provided by
an activated AIS target, the heading of the target appears on a chart
as a solid line attached to the AIS target symbol. A heading line does
not appear on a 3D chart view.
The projected course of an activated AIS target appears as a dashed
line on a chart or a 3D chart view. The length of the projected course
line is based on the value of the projected heading setting (
).
If an activated AIS target is not transmitting speed information, or
if the vessel is not moving, a projected course line does not appear.
Changes in the speed, the course over ground, or the rate-of-turn
information transmitted by the vessel can impact the calculation of
