CNS/ATM Gateway

Data link communications between aircraft and air traffic control (ATC) require an interface between air/ground data link networks and ATC systems that recognizes different message formats—both current and future. The ARINC ATC Gateway supports full automatic dependent surveillance (ADS) and controller-pilot data link communications (CPDLC) message sets, in accordance with existing standards and specifications.

For CPDLC, the Gateway allows the ATC end system to encode and decode bit-oriented messages in accordance with a standard protocol (RTCA DO-219). These encoded, two-way data link messages are then converted to ARINC 622 format and sent to the aircraft over the Aircraft Communications Addressing and Reporting System ( ACARS^®) network.

The Gateway also provides:

• Message-assurance
• Geographic filters that increase message-transfer efficiency
• Display of voice-position reports on ATC end systems
• Capability for bit-oriented messages to be converted to or from character-oriented messages for transfer over ACARS^®
• Hard copies of flight records
• ATC facility with aircraft data link capabilities
• Exchange of address information between ATC and aircraft

The CNS/ATM Gateway can be used as an ARINC stand-alone system or be integrated with an existing ATC system. Gateway modules are integrated with ATC equipment supplied by Aerospace Engineering, Alenia, Camp Systems, Hughes, Lockheed Martin, NITA, Northrop Grumman, Raytheon, Telephonics, and others.

FANS/DCL Connectivity

The ATC Gateway also serves as a connection point for granting Civil Aviation Authorities worldwide access to aircraft for delivery of AFN, CPDLC, and FANS messaging over ARINC GLOBALink and other Communication Service Providers.  The Gateway monitors aircraft location, last known service provider, and last media used so that unsolicited uplinks can be delivered with a high degree of confidence, even if flight-following measures are not being used by the originating agency.  ARINC has provisioned and manages robust connections from CAAs to the ATC Gateway in Europe, North America, Latin America/Caribbean, and Asia.
