Automatic Identification System
The Automatic Identification System (AIS) enables you
to identify and track other vessels, and alerts you to
area traffic. When connected to an external AIS device,
the chartplotter can show some AIS information about
other vessels that are within range, that are equipped
with a transponder, and that are actively transmitting AIS
information.
The information reported for each vessel includes the
Maritime Mobile Service Identity (MMSI), location, GPS
speed, GPS heading, time that has elapsed since the last
position of the vessel was reported, nearest approach,
and time to the nearest approach.
Some chartplotter models also support Blue Force
Tracking. Vessels being tracked with Blue Force Tracking
are indicated on the chartplotter with a blue-green color.
AIS Targeting Symbols
Symbol Description
AIS vessel. The vessel is reporting AIS infor-
mation. The direction in which the triangle is
pointing indicates the direction in which the
AIS vessel is moving.
Target is selected.
Target is activated. The target appears larger
on the chart. A green line attached to the
target indicates the heading of the target.
The MMSI, speed, and direction of the vessel
appear beneath the target, if the details
setting has been set to Show. If the AIS trans-
mission from the vessel is lost, a message
banner appears.
Target is lost. A green X indicates that the
AIS transmission from the vessel is lost, and
the chartplotter displays a message banner
asking whether the vessel should continue to
be tracked. If you discontinue vessel tracking,
the lost target symbol disappears from the
chart or the 3D chart view.
Dangerous target in range. The target flashes
while an alarm sounds and a message banner
appears. After the alarm has been acknowl-
edged, a solid red triangle with a red line
attached to it indicates the location and the
heading of the target. If the safe-zone collision
alarm has been set to Off, the target flashes,
but the audible alarm does not sound and
the alarm banner does not appear. If the
AIS transmission from the vessel is lost, a
message banner appears.
