Using AIS

Card 16

AIS uses digital radio signals to broadcast ‘realtime’
information between vessels and shore based stations
via dedicated VHF frequencies. This information is used
to identify and track vessels in the surrounding area and
to provide collision avoidance data. AIS will augment
your radar application, as it can operate in radar blind
spots.
In order to use the AIS feature, you will need a GPS and
compass for timing and position information together
with data from a suitable AIS receiver.

detailed data.

WARNING:

The AIS system displays other AIS equipped vessels in
the surrounding area as targets overlaid on a chart or
radar window. Up to 100 targets are displayed and are
scaled according to the size of the vessel. A vector
indicates the direction of travel of the vessel. As the
vessel’s status changes, the symbol for the target will
change accordingly.
You can view detailed AIS data, safety critical target
information, Alarm message (ALR) and Safety Related
Message (SRM) messages. You can also set up a safe
zone.

Sleeping target
Target not activated, dangerous or
lost.

Smaller vessels do not have to be
fitted with AIS and whilst it is
mandatory for larger commercial

vessels to carry AIS, its use is not. You
should not assume that your AIS will
display ALL vessels in your area.
