Display settings for AIS targets
You select how the AIS targets are displayed on the chart panel in the AIS Display settings
dialog.
• Velocity vector: Predicted position of the target in a specified period of time based on
the target's current speed and course over ground (SOG and COG). Time marks and steps
between each mark can be defined and added to the view
• Path predictor: Predicted vector based on speed over ground (SOG), course over ground
(COG) and rate of turn
• Past track: The target's track over a set time period. Time stamps can be added to the
track line
• True scale outline: Displays the targets as true scale symbols in large chart scale. The
displayed size is based on dimensions received in the target's AIS messages
• Heading line: The target's heading and eventually turn direction pointing in the direction
of the turn
• Range circles: Circles added relative to own vessel position to show the ranges where a
target is visible, active or defined as dangerous
• Target label: Target name as received in the AIS message
• Show AIS targets: Select to show specific AIS target types on the chart
• Show associated targets as AIS: Displays associated Radar/AIS targets as AIS. To enable
AIS/Radar targets associations, refer to "Configuring Radar targets" on page 43.
Configuring AIS targets
You specify the distance for when an AIS target should be activated and considered
dangerous from the AIS Configuration dialog. From this dialog you also define when a lost
AIS target are removed from the chart view.
