  1. Spectral Efficient COMmunications for future Aeronautical Services Jan Erik Håkegård jan.e.hakegard@sintef.no

  2. Outline • Background ATM/aeronautical communications • Why did we propose a project on ATM/aeronautical communications? • The SECOMAS project • Partners • Objectives • Activities

  3. 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 Source: Expectations of SESAR, Bernard Miaillier, D1 Forum • Increase by factor 2.4 • Today’s Air Traffic Management (ATM) systems are not capable • to support this increase

  4. 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

  5. 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

  6. 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

  7. 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

  8. Issues regarding satellite coverage in northern regions “The High North will be Norway’s most important strategic priority area in the years ahead. “ -Norwegian Ministry of Foreign Affairs • Large • 6 x land area • Mainly inhabited • A few islands • Economically important • Oil and gas • Fish • Shipping • Strategically important • Satellite coverage important

  9. Coverage GEO satellites

  10. Highly elliptical orbits (HEO)Molniya and Tundra

  11. SECOMAS project • Knowledge-building project • 2007-2010 • Working partners: • SINTEF • NTNU (The University in Trondheim) • Financial partners: • Norwegian Research Council • Avinor (The Norwegian ANSP) • Jotron • Kongsberg Defence Communications • Park Air Systems • Thales Norway

  12. SECOMAS objective • Explore spectrum efficient wireless communications • Meeting req. of future aeronautical comm. services at large • Including: • Links: Air-ground, air-air, satellite • Services: ATS, AOC/AAC, APS

  13. SECOMAS activities • Theoretical path (NTNU) • MIMO, ST-coding • Link adaptation • Cooperative and opportunistic transmission • Advanced channel coding • Multi-carrier transmission (e.g. OFDM) • Networking concepts • Cross-layer design • Industrial path (SINTEF) • Airport (IEEE802.16e) • Analytical approach • Simulations • (Validation through measurements) • Satellite component • ARTES-10 • Northern area coverage • Heterogeneous networks • Distribute traffic among various network options, respecting the services’ QoS requirements

  14. SECOMAS impact • Play a role in the development of future aeronautical communications • Get involved in international activities (SESAR, EC FP7, ARTES-10) • Academic results • Ph.D. student, scientific publications • Lead to development projects in cooperation with industry
