The mobile transponders are based on state-of-the-art aviation technology and form the cornerstone in networked systems. CNS Systems offers mobile transponders for airborne and vehicle installation.

Airborne Transponders
VDL 4000/A
VDL 4000/A is a multi-purpose data link developed for commercial transport aircraft. The transponder’s form factor is Arinc 600, and the interfaces are designed in accordance with Arinc 429. The transponder supports services for all phases of flight such that a complete gate-to-gate operation can be realised including applications for: departure clearance, 4D trajectory exchange, CPDLC, ATIS, and advanced surface movement, guidance and control operations. Services such as ADS-B, TIS-B, FIS-B and DGNSS augmentation (GNS-B) are embedded and fully supported by the transponder.

VDL 4000/GA
VDL 4000/GA is a multi-purpose data link designed to support the requirements of general aviation. The data link transponder provides ADS-B and supports other services, such as weather and traffic information, and has several interfaces to support a cockpit display of traffic information (CDTI).


  Vehicle Transponders
VDL 4000/AO
The VDL 4000/AO transponder has been developed to meet the stringent demands of safe surface movement operations and more efficient utilisation of airport resources. Based on aviation requirements, the transponder satisfies the most demanding applications in A-SMGCS. The vehicle transponder is optimised for A-SMGCS and ground handling applications.
