Section 6 Target Tracking and AIS 6-12
6.3.6 About display priority of AIS targets
Up to 180
*1
targets can be displayed in total of activated and sleeping AIS targets.
When there is an AIS target of 180
*1
or more, the display is made according to the following priority
order.
*1: The maximum number of AIS targets displayed can be changed to the option of 1000 targets.
If the number of targets at the same priority level exceeds the allowable maximum, they are displayed
in the following priority order:
6.3.7 Switching between ground vector and water
vector
The vector of an AIS target is to be displayed with a vector over ground or over water by switching the
stabilisation mode. The type of the currently displayed vector can be confirmed by viewing the setting
of the stable mode.
When [GND] is selected for the stabilisation mode: Ground vector
When [Sea] is displayed for the stabilisation mode: Water vector
When the vector of an AIS target is displayed with a vector over water, the system has converted the
AIS target's vector over ground to the vector over water according to the data received from the AIS
and the own ship's information.
1. Association target
2. Activated AIS target
3. Sleeping AIS target

(Target as a dangerous ship for which an alarm has been generated)
3. Target in automatic activation zone
4. Activated AIS target
5. Target inside AIS filter
6. Target outside AIS filter
