Operation
AIS on a connected chart plotter
The AIS receiver receives data as soon as the VHF radio is switched on. If
equipment supporting AIS data over NMEA is attached to the VHF radio, it
starts plotting the targets received.
AIS information transmitted from vessels with class A and B transponders
includes static and dynamic information.
Static information:
•
Name
•
Type of vessel
•
Call sign
•
MMSI number
•
IMO number
•
Draught
•
Size of vessel
Dynamic information:
•
Vessel position
•
Speed over ground (SOG)
•
Course over ground (COG)
•
Rate of turn (ROT)
•
Heading
•
Status
•
Destination
•
Estimated time of arrival (ETA)
Note that not all vessels transmit all of the above information. Besides AIS
data from class A and B vessels, base station information, safety broadcasts
and other AIS message types can be received.
The AIS receiver is enabled by default. It can be turned off to reduce power
consumption. For instructions how to turn it off see
System setup
on page 67.
