AIS DATA

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 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.

and target flashes.

 

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 message (ALR) and Safety Related Message (SRM) messages. You can also set up a safe zone.

Calculated CPA/TCPA value uncertain.

Lost target

When signal of a dangerous AIS target not received for 10 seconds.

Target orientated in COG or CSE direction as appropriate.

Alarm sounds and target flashes

WARNING:

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.
