Section 6    Target Tracking and AIS  6-14 
 
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 
stabilization 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 stabilization mode: Ground vector 
When [Sea] is displayed for the stabilization 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. 
 
6.3.8  Association Target Symbols 
Only a few targets transferred from the radar will be designated as associated targets and following 
radar conventions the symbol for AIS Priority will be the default symbol.
