14. AIS
AIS is an Automatic Identification System. It has been introduced to improve the safety of
navigation by assisting in the efficient operation of ship-to-ship location reporting and VTS
applications. The system should enable operators to obtain information from the ship
automatically, requiring a minimum of involvement of ship’s personnel, and should have a high
level of availability. AIS transponders installed on IMO vessels use VHF frequencies to:
· Transmit details of their own vessel
· Receive details from other vessels or navigation aids within VHF range.
STANDARD HORIZON GPS Chart Plotters are able to display AIS target (for collision
avoidance) on the Chart Page and AIS list pages when connected to a AIS receiver
(GX2100 or GX2150 STANDARD HORIZON VHF/AIS transceiver) or transponders which
output NMEA 0183 VDM sentence at 38400 or 4800 baud. The Chart Plotters are able to
show targets from both Class A (commercial) and Class B targets.
