Section 6 Target Tracking and AIS 6-44
6.6.2.2 Automatic activation
Activate an AIS target in automatic mode to display the vector and heading line.
When the automatic activation function is used, AIS targets are automatically activated when they go
into the automatic activation zone. The automatic activation zone is identical to the automatic
acquisition zone (AZ) used for target tracking. For the zone setting, refer to "6.5.1.1 Automatic
acquisition ".
Note
When the AIS target's symbol is activated but the vector is not displayed, the following are
probable causes of the trouble:
• COG/SOG is not input yet from the GPS.
• The selected speed sensor is malfunctioning.
Memo
The bearing or range in the acquisition/activation zone shall be based on the position of the radar
antenna.
If there are more AIS targets than the allowable maximum, they are deactivated from the
low-priority (Refer to "6.3 Displaying Symbols").
