SESAR position on ATM Communication Technologies
and future trends

• Kors VAN DEN BOOGAARD, SESAR CIT
• Hanspeter KULHEN, SESAR Task 2.5 R - EADS Astrium
• Cedric DSILVA, SESAR Task 2.5.2 O - Thales

Background

• Todays ATM system is built on technology
• sometimes there are overlapping capabilities, and
  unnecessary fragmentation
• It relies on highly skilled human-centered
  control to achieve safe separation.
• Technological advances in conjuntion with a futre
  ATM concept are needed to support air transport
  growth
• Technology will support a future CNS-ATM
  infrastructure - the Enablers of future of ATM
  services need to be considered
• Choices must be coordinated and rationalised
• Transition steps to be recognised period during
  which coexistence of new and legacy componentsmay
  not yet giving full potential benefits.

C - N - S technologies in the ATM context
their purpose

• NAV materialise an maintain position from
  point-A to point-B

• SUR control/verify that a/c is where it should
  be

• COMM corrective action, tactical
• (also strategic updated flight information)

SESAR task 2.5.2 approach

• SESAR TASK 2.5 establishes its material in two
  steps
• Initially, for D1, identify the current
  technological status, including the ongoing and
  future trends
• During D3, participate in the definition and
  selection process of the future 2020 CNS-ATM
  system, where concept (2.2) and system
  architecture (2.4) needs will be analysed
  against technological capabilities for the future
  (2.5).

Summary regarding the CURRENT SITUATION

• Gnd-Gnd (fixed comm.)
• Intra-ANSP links (local choice low or no
  international standardisation)
• Cross-Border links ICAO standards (AFTN, CIDIN)
• COTS products compatible with service
  providers/operators market technologies (i.e. IP
  over cable or Fibre, VSAT also for remote fixed
  voice and data communication).
• Air-Gnd (mobile comm.)
• Voice VHF 25 kHz and 8.33 kHz
• Data comm. VDL2/ATN initial data communication
  standard
• Oceanic / remote HF is the authorised aviation
  link SATCOM used for voice and data.
• Radio spectrum is scarce resource
• efficiently coordination and management needed
  today
• Coordinate planning to prepare future
• To support limited growth, short-lived gap-filler
  solutions exist today, BUT THE NEXT GENERATION
  ATM MUST BE PREPARED NOW

On-going TRENDS, as established at D1

• Migration from analogue to digital (mobile and
  fixed communication)
• Ground fixed comm. IP and VOIP
• Mobile comm
• Continental ATC data ( e.g. L2000)
• Oceanic/Remote (SATdata, HFDL)
• SatCom voice for primary use is also under study
  in oceanic and remote areas. / HF voice remains
  as backup
• Different Communications needs
• performance is dependant on application type
• ATC, ATC, and APC are not seeking the same
  performance areas

Longer-term FUTURE TRENDS, as established at D1

• Communication
• is a key part of a robust C-N-S / ATM system
  comm. reactivity (performance of the control
  loop, resilience to failure) is an essential
  partof a future ATM system, in a modernised
  concept where higher capacity is sought.
• it is also needed for ATM co-operative concepts
  and for Information management.
• Today intrinsic "work or fail" nature of all
  technologies lead to constraining procedural
  reversions
• Degraded and failure modes in the future should
  not extensively lower the ATM system capability
• Future systems must be robust
• Long-term
• Data becomes the primary means of communication
  and supports automation
• Information integration from all actors within
  the ATM network.
• Voice services are mainly retained for backup
• Security becomes highly relevant for voice and
  data communications.
