Class A AIS Mobile

The VDL 6000 AIS Class A System is compliant to the International standards ITU M.1371-1 and IEC 61993-2 as applicable for SOLAS vessels.

The VDL 6000 is robustly designed with technology used in C.N.S Systems civil aviation products with its special demands on quality, performance, safety, security and traceability.

The VDL 6000 system consists of three basic building blocks; Transponder, MKD and Connection Unit (including connecting cables). The system is optionally delivered with antennas, antenna cables and connectors.
The VDL 6000 system is based on a digital radio module, high performance processors, robust software and a compact design.
