ICT ONERA, Toulouse, France, 6. November Outline Background ATM/aeronautical communications Why did we propose a project on ATM/aeronautical communications? The SECOMAS project Partners Objectives Activities
ICT ONERA, Toulouse, France, 6. November Increase by factor 2.4 Today’s Air Traffic Management (ATM) systems are not capable to support this increase Why are new ATM systems necessary? Traffic in million flights per year Peak day flights by commercial airlines flights by general aviation aircraft Numerous military aircraft Estimated traffic in million flights per year Peak day flights by commercial airlines flights by general aviation aircraft Numerous military aircraft Source: Expectations of SESAR, Bernard Miaillier, D1 Forum
ICT ONERA, Toulouse, France, 6. November 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: MHz (no system proposed) L-band: Portions within the MHz (L-DACS1/2/(3)) C-band: Portions within the MHz (IEEE802.16aero) Develop a satellite component for ATM ARTES-10
ICT ONERA, Toulouse, France, 6. November 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 OptionsAccess Scheme Modulation Type Origins L-DACS 1FDDOFDMB-AMC, P34 L-DACS 2TDDCPFSK/GMSKLDL, AMACS
ICT ONERA, Toulouse, France, 6. November C-band Airport communications Develop an aeronautical Mobile WiMAX standard (IEEE802.16aero) Identify the portions of the IEEE e 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
ICT ONERA, Toulouse, France, 6. November 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
ICT ONERA, Toulouse, France, 6. November Issues regarding satellite coverage in northern regions Large 6 x land area Mainly inhabited A few islands Economically important Oil and gas Fish Shipping Strategically important Satellite coverage important “The High North will be Norway’s most important strategic priority area in the years ahead. “ -Norwegian Ministry of Foreign Affairs
