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 D`SILVA, SESAR Task 2.5.2 O - Thales Avionics
Page: 2 Date 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.
Page: 3 Date 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) A B A B
Page: 4 Date 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). current situation 2005 2010 201520202025 on-going trends future plans
Page: 5 Date 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
Page: 6 Date 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
Page: 7 Date 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.
