The vector of an AIS target is to be displayed with a vector over ground or over water, depending on the speed
sensor setting and current offset setting. The type of the currently displayed vector can be confirmed by
viewing the setting of the stable mode.
When GND is displayed for the stability mode (upper left of the display on page 2-2):
Vector over ground
When Sea is displayed for the stability mode (upper left of the display on page 2-2):
Vector over water
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.
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 yet input from the GPS.
The selected speed sensor is malfunctioning.
