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 (Option)
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. (NCA-877WA)
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.
