AIS TGT Capacity Limit
100% of the maximum number of acquired AIS targets are being tracked.
Remedy: Delete at least one unimportant AIS target.
AIS New Safety Message
The AIS has received a safety message.
The safety message can be read under > Tools > Target > Message.
AIS No Valid COG
The AIS system has no valid course over ground information.
Remedy: Check the connected sensor and cabling. (Typically the COG information from an inte-
grated bridge system which is derived from a GPS sensor, the AIS will continue to work but will
transmit less information to other ships.)
AIS No Valid Heading
The AIS system has no valid heading information from the sensor.
Remedy: Check the heading sensor. (Typically the heading information from an integrated bridge
system which is derived from the gyro, the AIS will continue to work but will transmit less informa-
tion to other ships.)
AIS No Valid Position
The AIS system has no valid position information from internal position sensor
Remedy: Check the cabling and the antenna of the internal GPS sensor. (Typically the position
information from an integrated bridge system which is derived from a GPS sensor, the AIS will
continue to work with its own sensor, but the position, which is sent out to other ships might not
be as accurate as before)
AIS No Valid ROT
The AIS has no valid rate of turn information from the sensor.
Remedy: Check the sensor and the cabling. (Typically the rate of turn information from an inte-
grated bridge system which is derived from the gyro, the AIS will continue to work but will transmit
less information to other ships)
AIS No Valid SOG
The AIS has no valid speed over ground information.
Remedy: Check selected speed sensor. (Typically the SOG information from an integrated bridge
system which is derived from a GPS sensor, the AIS will continue to work with its own sensor, but
the speed, which is sent out to other ships might not be as accurate as before)
AIS Offline
Remedy: Check the AIS system. It might be possible to eliminate the fault by switching the voltage
supply to the AIS electronics unit off and then on again at the ship's mains.
