Outline
  • Background ATM/aeronautical communications
    • Why did we propose a project on ATM/aeronautical communications?
  • The SECOMAS project
    • Partners
    • Objectives
    • Activities
why are new atm systems necessary
Why are new ATM systems necessary?
  • Traffic in 2005
    • 9.2 million flights per year
    • Peak day
      • 30 000 flights by commercial airlines
      • 200 000 flights by general aviation aircraft
      • Numerous military aircraft
  • Estimated traffic in 2025
    • 22 million flights per year
    • Peak day
      • 72 000 flights by commercial airlines
      • 480 000 flights by general aviation aircraft
      • Numerous military aircraft

  • Increase by factor 2.4
    • Today’s Air Traffic Management (ATM) systems are not capable
    • to support this increase
what is the impact on the communication systems
What is the impact on the communication systems?
  • Bandwidth congestion
    • Primarily in the VHF band
    • High density airspace (e.g. Continental Europe)
  • Solutions:
    • Increase spectrum efficiency in the VHF band (8.33 kHz channels)
    • Migrate from voice communication to data communication (VDL 2/3/4)
    • Open new frequency bands for aeronautical communication (WRC-07)
      • VHF band: 108-118 MHz (no system proposed)
      • L-band: Portions within the 960-1164 MHz (L-DACS1/2/(3))
      • C-band: Portions within the 5000-5150 MHz (IEEE802.16aero)
    • Develop a satellite component for ATM
      • ARTES-10
l band digital aeronautical communication system l dacs
L-band Digital Aeronautical Communication System (L-DACS)
  • Future Communication Study (Eurocontrol/FAA)
  • Two alternative solutions LDACS-1 and LDACS-2
  • Conclusions presented to ICAO in October 2007
  • Decision on one system to be taken in 2009
  • Deployment in 2020
c band airport communications
C-bandAirport communications
  • Develop an aeronautical Mobile WiMAX standard (IEEE802.16aero)
    • Identify the portions of the IEEE 802.16e standard best suited
    • Identify and develop missing required functionalities
    • Evaluate and validate the performance through trials and test bed development
    • Propose an aviation specific standard
satellite component
Satellite component
  • Two ARTES-10 (ESA) studies (K.O. Dec 2007)
    • Communication System Design
    • Analysis and Definition of Satellite System
  • Objectives
    • Preparation work to support the SESAR Master Plan
      • Must be coherent in time and content with the SESAR program
  • Support frequency allocations
  • Consider non-technical issues from the start
  • Define ancillary payload
issues regarding satellite coverage in northern regions
Issues regarding satellite coverage in northern regions

“The High North will be Norway’s most important strategic priority area in the years ahead. “
