5.1  PREPARATION 
 
 
This section explains the features of the target tracking and AIS functions, and the initial setting for using each 
function. 
 
 
 
Target Tracking Function 
 
The target tracking function calculates the course and speed of a target by automatically tracking the 
target's move.   
The target tracking function enables the automatic acquisition of targets by using the automatic 
acquisition zone function.     
The target tracking function also enables the simulation of the ship maneuvering method to avoid 
collisions by using the trial maneuver function. 
If the mode is ground stabilization, SOG/COG used for own ship's information in target tracking. If the 
mode is sea stabilization, SPD (speed through the water) / HDG (heading) used for own ship's 
information in target tracking. 
 
Maximum tracking range is 32nm. (Available all range scale) 
 
 
AIS (Automatic Identification System) function 
 
The AIS function shows the target’s information on the radar display, using other ship's information sent 
out from the AIS unit.
