The implementation of Data Link is key to increasing Air Traffic Control (ATC) efficiency and capacity. The Aeronautical Telecommunications Network (ATN) provides the communications technology to support these Data Link enabled ATC services.
The European Commission has designated ATN/CPDLC a mandatory component on all aircraft flying in European airspace (Commission Regulation (EC) No 29/2009) and ANSPs must support CPDLC for all aircraft operating in EU airspace by 2015. The regulation also covers the operation of some aircraft which are equipped with FANS/CPDLC Data Link system.
Airtel ATN specialises in data communications solutions for the aviation industry and has been providing Data Link systems since 1993. Airtel’s ATN/FANS Data Link Solutions for Air Navigation Service Providers include:
Air/Ground Data Link Server (AGDLS)
The ATN Air/Ground Data Link System (AGDLS) is responsible for handling Data Link communications. It supports ATN communications application such as Context Management (CM), Controller Pilot Data Link (CPDLC), ADS-C (Automatic Dependent Surveillance and Flight Information Services (FIS). These applications provide support for ATC services such as Data Link Initiation Capability (DLIC), ACL (ATC Clearance), ATC Communications Management (ACM) and ATC Microphone Check (AMC).
The AGDLS comes in two main configurations:
- Data Link Front End Processor (DL-FEP): FDPS implements the data link services and the DL-FEP handles message formatting and communications with the aircraft.
- Data Link Server (DLS): DLS also implements ATC services, simplifying the implementation in the FDPS.
