What is AIS?
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
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.

How is AIS data displayed?
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 messages (ALR) and safety related
messages (SRM). You can also set up a safe zone.

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.
