Tracking section
The AIS label shows the AIS operating mode. If an AIS device is connected, a progress bar in-
dicating the number of targets will be displayed, otherwise the information displayed is “OFF”
(See “System data area sections” on page 23). The maximum number of targets that can be
acquired is 300 (CAT1&2) or 120 (CAT3); reaching 95% of the maximum, the progress bar will
change to yellow, to warn about the near limit. And reaching 100% it will change to red, to
indicate the reached limit. It is possible to set the priority of AIS targets by their Range, CPA
and TCPA. It is also possible to filter AIS targets by Range, CPA, TCPA, CLASS A, CLASS B and
Speed. Detailed explanations about AIS priority and filtering are provided at “Operating” on
page 93. The General AIS information are provided in “AIS (Automatic Identification System)”
on page 91.
Target tracking
The TT label indicates how many targets have been acquired. If there are no acquired targets,
the label will indicate “STBY”. Otherwise, a progress bar indicating the number of targets will
be displayed. As for the AIS label, reaching 95% of the maximum targets that can be pro-
cessed (100 for CAT1&2, 20 for CAT3), the progress bar will change its color to yellow, and
reaching 100% it will become red.
Target track and AIS association mode
A symbol is displayed to indicate the data source when an associated target is selected.
CCRP Position (Consistent Common Reference Point)
By pressing this button it is possible to change the CCRP position between
the conning position and the radar antenna.
Every measurement made with cursor, or EBL VRM etc. is always referred to CCRP. The PPI
origin is always on the radar antenna position, in both modes.
By pressing this button it is possible to change the CCRP position between the conning posi-
tion and the radar antenna position. Changing the CCRP position will modify the reference of
any angles and distance measurements e.g. bearing scale, range rings, targets distance, ERBL,
etc.
For optimal CCRP presentation the radar sensor should be aligned in position and every range
delay or azimuth skew should be compensated. These settings are made during the installa-
tion setup and all the radar display configuration can be saved and shared with other displays
via a USB memory module.
When the selected transceiver is changed, the configuration for that unit is automatically read
from the setup and applied to the picture so that the PPI center is consistent for all selected
radar TXRX and for each console on the bridge.

Note:
In True Motion and when the CCRP, due to the position of the radar antenna or the
range scale in use, is located at more than 50% of the PPI radius, the Reference will change
automatically to Antenna Reference. When this condition is not true anymore, because the
range scale was changed, the reference is again automatically switched to the CCRP. This
check is made to avoid loss of radar PPI visibility in front of the ship or incorrect presentation
of the bearing scale.
