VelocityTrack settings
Use this dialog to set speed thresholds of targets to be colored.
The speed threshold can be defined to apply for the radar source of the selected radar panel
only, or to all radar sources connected to the system. The setting is only applied to those
radars powered and connected at the time the setting is made. If the all radar sources option
is selected, newly connected radars will use the specified values automatically.
VelocityTrack examples
Approaching and diverging moving targets can be indicated as neutral (not colored) in some
circumstances. The navigator should be aware of these situations to safely use the
VelocityTrack feature as an aid for collision avoidance.
Examples of how VelocityTrack behaves in 2 navigation scenarios is illustrated below. The
illustrations show a target (
A
) crossing own vessel's (
B
) path.

The examples show the target movement (1-5) over 5 radar scans with the radar in relative
motion mode.
In example
C
, own vessel COG is 0°, and speed is 0 knots.
In example
D
, own vessel COG is 0°, and speed is 10 knots.
In both examples, the target COG is 270°, and the speed is 20 knots.
The colors in the examples are according to the colors used for black/green and black/yellow
radar palettes:
•
Red (
C1
/
C2
and
D1
/
D2
), indicating the target is on an approaching path to own vessel. Its
relative speed at that point is greater than the VelocityTrack speed threshold.
•
Not colored (
C3
and
D3/D4
), indicating it is temporarily neutral because its relative speed
at that point is less than the VelocityTrack speed threshold.
•
Blue (
C4
/
C5
and
D5
), indicating the target is diverging away from own vessel and its
relative speed at that point is greater than the VelocityTrack speed threshold.
Radar symbology
Radar symbology defined in the Radar Settings panel can be turned on/off collectively. See
the radar panel illustration showing optional radar items.
