ATN: the Aeronautical Telecommunications Network
ATN,or the Aeronautical Telecommunications Network, is a worldwide network infrastructure designed to support all types of aviation air-ground communications. ATN is currently used in Europe for CPDLC applications (ATN Baseline 1) and also for enhanced Air Traffic Services (ATN Baseline 2), including the Initial 4-Dimension Trajectory concept (enhanced route clearances; 4D trajectory negotiation with ATC).
The current ATN infrastructure relies on the OSI (Open Systems Interconnection) model. However, evolutions are ongoing to implement an IP-based network infrastructure supporting ATN applications: ATN/IPS (Internet Protocol Suite).
The IPS infrastructure will provide an air-ground network offering higher reliability and increased security for both ATC and AOC communications. ATN/IPS will offer a more secure air/ground link between aircraft and ground stations, and will improve the security of the end-to-end transmission of ATC and AOC applications.
The ATN/IPS targeted subnetwork will additionally offer improved datalink performance as well as higher bandwidth. IPS will utilize multiple air-ground links, including the legacy VDL Mode 2 link, Future SatCom (such as SwiftBroadband, Iris Service Evolution), LDACS, and AeroMACS. The implementation of the ATN/IPS network will serve as an enabler for several technological concepts such as 4D-Trajectory-based operations and performance-based operations.
