The VDL 6000 transponder can function either as an AIS Class A transponder or as a combined AIS Class A/Inland transponder, depending on its factory configuration (each variant can also be configured as a ‘receive only’ unit).
The VDL 6000 transponder interconnects with existing onboard sensor equipment such as GNSS, Gyro and optionally a Rate of Turn (ROT) gyro via the sensor interfaces. From these sensors information on position, COG, SOG, ROT, heading etc. is sent to the transponder and compiled into position report messages, which are broadcast regularly on the VHF data link.
The transponder also supports broadcast and addressed transmission of text messages, and distribution of other types of information serving as a generic data link.
The transponder supports connection to other onboard equipment, such as an ECS/ECDIS system, in order to display the received data in a clear way. This requires however that the external equipment supports AIS information.
The VDL 6000 transponder provides additional interfaces for configuration and maintenance purposes, connection of a long-range communication device and a Pilot’s laptop.
