Advanced Technologies for Networking in Avionic Applications

Two groups of the institute are contributing to ATENAA: The Optical Communications Group inside section Digital Networks and the Antenna Group of section Navigation.

The ATENAA project is aimed at the following objectives:

• Define the concept for a future networked avionic environment including both moving platforms (aircraft and satellites), ground infrastructures and the related users and communication systems
• Evaluate and develop the technologies needed for the management and the security of the avionic network
• Assess a common set of requirements and the HW and SW technologies needed for:
  • enhancing the performances of present avionic communication systems (in terms of efficiency, transmission speed, etc.)
  • implementing the future avionic communication systems to be used in the avionic network
• Test and validate emerging communications technologies against their applicability in the realisation of broadband communication systems for the avionic networked environment:
  • HW technologies for Ka-band communication systems (with particular reference to TX and RX avionic phased array antenna realisation)
  • HW technologies for optical communication systems (both for outside-aircraft data links realisation and for inside-aircraft broadband bus implementation)
• Evaluate the overall performances and define a common baseline for the future demonstration and implementation of the avionic network

The Optical Communications Group is contributing on...

• Studying the applicability of free-space optical link technology for highspeed avionic communications
• Outer optical link communications system architecture
• Setting up a demonstrator for outer optical link validation

The acitivities of the Antenna Group include

• Subsystem specifications for Tx-antenna
• Radiating element selection
• Array definition and simulations
• Array design and integration
• Study and simulations
• Antenna test and validation
