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 Trasponders 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.
Product description
The VDL 4000/A is a multi-purpose data link transponder developed for advanced CNS/ATM applications that depend on reliable and time-critical information.
The core function provided is Automatic Dependant Surveillance - Broadcast (ADS-B) but other features such as point-to-point communication and various broadcast services are supported, enabling a wide range of applications including 4D Trajectory down links.
The transponder is intended for installation in commercial aircraft and operates in accordance with the ICAO standard for the VDLMode 4 digital radio link.
The form factor of the transponder corresponds to the Arinc 600 standard and includes Arinc 600 connectors and Arinc 429 interfaces. The transponder is certified and delivered with an EASA Form 1 tag. This certification level allows the equipment to be used onboard aircraft for non-safety-critical applications.
Mobile transponders can operate autonomously outside the coverage of ground stations, whereas the addition of ground stations and a ground-based network provides increased functionality and capabilities.
The transponder supports services for all phases of flight such that a complete gate-to-gate operation can be realised including the following applications: departure clearance, 4D trajectory exchange, CPDLC, ATIS, and advanced surface movement, guidance and control operation. Services such as ADS-B, TIS-B, FIS-B and DGNSS augmentation (GNS-B) are embedded and fully supported by the transponder.
