VDL 6000/FASS (Fixed AIS Station System)

C.N.S. Systems introduces an extremely flexible product for AIS shore station operation, the VDL 6000/FASS.

Our VDL 6000/FASS can easily be configured according to specific customer needs, from a basic unit to a fully redundant system with an embedded controller providing extensive processing and logging functionality.

Independent of the configuration, our VDL 6000/FASS is an excellent choice and offers great performance and quality at a very attractive price.

To be able to guarantee a cost-effective solution, our VDL 6000/FASS is remotely controlled and the software can also be remotely updated. The system includes one or two fixed AIS stations, each corresponding to a Physical Shore Station (PSS) as defined by IALA A-124.

The optional embedded controller offers functions such as:

• Possibility to define specific data filter criteria.
• Log data locally in the shore station.
• SNMP agent for network management.
• AIS messages for virtual Aids to Navigation.

The VDL 6000/FASS is the perfect choice for the maritime authority implementing an AIS network, but it is also suitable for stand-alone operation at a VTS or a port.

The benefit of AIS is not limited to the surveillance aspects; it is also possible to offer dedicated services to the increasing number of ships equipped with an AIS transponder.

Our VDL 6000/FASS together with our customer-specific software package is a guarantee for a cost-effective total solution.
