D Status of the vessel icon
There are 5 kinds of target vessel status.
Sleeping target:
The AIS signal has been updated (received),
but the distance from your vessel is far, or you
set it as 'sleeping.' The target is displayed as
just a triangle without a heading or vector line.
Activated target:
The target is displayed with the heading line,
SOG (Speed Over Ground), COG (Course
Over Ground) vector and ROT (Rate of Turn).
SOG (Speed Over Ground) and
COG (Course Over Ground) vector
Heading line
If there is no heading data, the line points
in the direction of COG.
Dangerous target:
Even if the target's status is sleeping or
activated, when it enters your CPA and TCPA
limit settings, the target is displayed with a
thick line and changes its color to red.
Selected target:
The target's information is displayed in the
data area.
Lost target*:
When the AIS signal has not been updated
(received) for a specific time period, the target
triangle is marked with a red cross.
If the AIS signal has still not been updated
(received) for 6 minutes and 40 seconds, the
target icon disappears.
* A vessel is regarded as a "Lost target" after a
specified period of time has passed since the
vessel last transmitted data. (p.29)
ROT (Rate of Turn)
D Plots (AIS)
The plot displays the activated target, SAR, SART,
MOB, or EPIRB's past positions as 5 dots, during
each specified tracking interval.
• The target track may change, depending on the setting in
the "Track Interval" item of the Target menu. (p. 31)
