course line does not appear. Changes in the speed, course over ground, or
rate of turn information transmitted by the vessel can impact the calculation of
the projected course line.
When course over ground, heading, and rate of turn information are provided
by an activated AIS target, the projected course of the target is calculated
based on the course over ground and the rate of turn information. The
direction in which the target is turning, which is also based on the rate of turn
information, is indicated by the direction of the barb at the end of the heading
line. The length of the barb does not change.
When course over ground and heading information are provided by an
activated AIS target, but rate of turn information is not provided, the
projected course of the target is calculated based on the course over ground
information.
Showing AIS and MARPA Vessels
Before you can show AIS vessels on a chart, you must have an external AIS
device and active transponder signals from other vessels. Mini Automatic
Radar Plotting Aid (MARPA) functionality works with radar.
You can configure how other vessels appear on a chart or on a 3D chart view.
The display range and MARPA settings configured for one chart or one 3D
chart view are applied only to that chart or to that 3D chart view. The details,
projected heading, and trails settings configured for one chart or one 3D chart
view are applied to all charts and to all 3D chart views.
