5 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Item 3 - Overview of Satellite Communication Activities to date

6 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 The European problem ! 3-1

7 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 2015 2002 VHF situation in Core Europe Capacity Vs Traffic needs The Aeronautical Mobile Communication infrastructure needs, in congested airspace, to accommodate Traffic growth 8.33 over FL 245 in ECAC We will be somewhere here with 8.33 below FL 245 Capacity demand Ideal case: ALL airspace in 8.33 In any case a gap will exist What is the foreseen situation for communication resources in Europe Additional communication capacity needs to be made available outside the VHF band 3-2

8 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Increasing Requirements 3-3 The Aeronautical Mobile Communication infrastructure needs also to evolve to support new ATM Concepts : however still relying on voice exchanges for emergency and non-routine exchanges. Increasing flight safety, security and efficiency based on data exchanges,

9 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Avoiding coverage gaps For efficiency, ATM/CNS should be homogeneous Terrestrial infrastructure is not economically feasible everywhere 3-4

10 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Options Communication capacity has to be made available outside the VHF band which is close to saturation in Europe - even with 8.33kHz channels Eurocontrol is pursuing two options - terrestrial-based using UMTS-type technology satellite-based using enhancement of existing AMSS as a Next Generation Satellite System - NGSS –applicable to Europe and the rest of the world Timescale is be operational by 2010 to 2015 3-5

11 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 3-6 Eurocontrol Strategy The Eurocontrol Communication Strategy already refers to satellite services to support voice and data services Extract from Eurocontrol Communications Strategy - Enhanced air-ground data links:…... New satellite systems may offer cost reduction opportunities with increased performance and availability.

12 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Operating concept 3-7

13 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Among candidate systems, geostationary satellite-based technologies are considered promising due to their : global nature - with global beams regional nature - with regional/spot beams adaptability to specific airspace (e.g. low density/oceanic airspace, upper airspace) adaptability to support specific services (e.g. ground-to-aircraft broadcast). capability to complement terrestrial systems (thus reducing pressure on the VHF spectrum) Why satellite systems ? 3-8

14 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 What choices are there ? There are several current (e.g. ICAO AMSS) or emerging satellite technologies (e.g. Iridium) but they are designed to support shared use or non-safety traffic only Some support AAC, APC - some may support AOC and ATSC as well (e.g. AMSS) No system supports only AMS(R)S Previous experience has shown that reliance on a shared business case can cause problems Where safety and regularity of flight communications are to be carried by a communications system specific measures must be put in place to safeguard them 3-9

15 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 What About the Current AMSS? Due to historical design choice, the current AMSS has limitations Designed to meet full range of users leading to more complex system design Expensive aircraft installation and avionics Limited number of Large Ground Earth Stations (GES) leading to limited options for communications service provision No Guaranteed service restoration delay after interruption Shared use of spectrum between safety and non-safety services Perceived as only applicable to low density traffic areas due poor performance……but 3-10

16 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Reuse and improve A good infrastructure has been built-up so lets re-use it GEO Satellites GESs Spectrum in L-band Terrestrial networks Institutional arrangements but improve on it by... 3-11

17 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Next Generation Satellite System Low cost AES by tailoring the system to meet safety and regularity of flight communications only Use of newer techniques e.g. CDMA to improve multiple access and overall efficiency Two levels of service - global (low rate) and regional (higher rate) Option to use Ku-band feeder links enabling small GESs can be deployed locally without extensive ground network Design in high levels of availability, reliability and continuity required for safety and regularity of flight communications 3-12

18 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Initial Deployment in ECAC Existing resources 3-13

19 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Evolution if/when required Additional capacity VSAT Access 3-14

20 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Example Spot beam coverage ARTEMIS 3-15

21 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 High level Requirements for an Next Generation Satellite System 3-16

22 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Capacity and coverage ATM concepts seem to need modest instantaneous throughputs - these can be met by a medium rate highly reliable communication system (approx. ~1 kb/s* for data) Provide anytime, anywhere a minimum communication capability to the users (~7 kb/s per aircraft) Flexibility to increase the capacity in specific areas (e.g. regional beams) (~30 kb/s per aircraft) Relieve terrestrial systems in congested areas 3-17 *Eurocontrol Report Operating Concept for the future mobile communication infrastructure - D2

23 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 High levels of availability, reliability and continuity required for safety and regularity of flight communications ATS Voice - emulate VHF R/T and party-line Data - meet needs to support ODIAC services plus specific protocols for periodic short data messages (e.g. ADS) and also broadcast information AOC Voice - meet continuing need for voice communications Data - support increasing exchange of data messages Supported Services 3-18

24 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 3-19 Requirements to be satisfied Unique technical standard to guarantee interoperability worldwide Capability for accommodating multiple competitive communication service provision –User would choose his provider where a choice exists –Connectivity should be transparent to service provider choice Capability for communication service providers to choose their satellite capacity supplier –Signal in space is standardised in the Service band (L-band) –Feeder links are an implementation issue Fixed network deployment –Must satisfy the overall connectivity requirements –Interoperability to be satisfied irrespective of standards in the ground segment Service Provision

27 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 3-22 Implementation scenario Complement to the terrestrial system (which will stay for the foreseeable future) is a key feature The goal is that the NGSS has a similar Quality of Service to VHF voice systems, therefore the transition between the two should be easier, if not transparent

28 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 3-23 Costs Avionics cost at affordable level (similar to VHF) for aircraft ranging from GA to airliners specifically tailored to requirements economies of scale Minimize the up-front investment for infrastructure Initially use existing space segment (e.g. Inmarsat) Minimal changes to existing GESs Communication costs a regional resource of dedicated capacity Stakeholder buy-in from an early stage reduce retrofit costs

29 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Spectrum Requirements Spectrum requirements are dependent on applications (ATS - Voice & Data; AOC Voice & Data) Initial estimates show that approximately 4 MHz are needed in ECAC using a regional beam Operates in the L-band (1.5 / 1.6 GHz) where aviation is a privileged user but under threat There is guaranteed long term availability of global coverage for safety communications due to IMO (Maritime) obligation to support GMDSS 3-24

30 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 International Activities outside Europe 3-25

41 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Institutional issues Standardisation new satellite systems capability needs to be standardised for worldwide operation confirm that NGSS SARPS are appropriate - seem so at initial review Access control to space segment - who, how ? Use of AMS(R)S spectrum with many service providers GES operators detailed technical standards co-ordination between them e.g. use of codes, hand-overs, etc 6-3

42 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Business aspects Targeted at AMS(R)S therefore has to be paid by ATSPs and airlines only e.g. no APC traffic revenues however it is not vulnerable to market failure Business case is expected to consider flexible service provision mechanisms goal of making costs significantly lower than AMSS (particularly avionics) which were due to limitation to AMS(R)S usage identification of benefits including do nothing option comparison of technology solutions 6-4

43 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Technical Aspects Technical design concepts are well advanced in ESAs SDLS concept but still open to refinement Finalisation of design in consultation with aviation community including you - Verify technical asssumptions Data rate - is it adequate to meet requirements (AOC is less clear)? Use of Polling Service - how is it used ? Satellite RF link - need for efficient use of spectrum ATSC voice service –design of human interface for access –party line acceptance 6-5

44 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 Next short term steps A first version of the system description (in ICAO Circular and Technical Manual format) Planned to be finalised end Dec 02 Proposed to be reviewed by E-mail with volunteers by mid Jan 03 To be presented to AMCP8 (Feb 03) for requesting restart of ANC NGSS task Demonstration plan European demonstrations 11th ICAO Air Navigation Conference - September 2003 Others ? 6-6

45 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 AMS(R)S Spectrum Defence 6-7

46 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 AMS(R)S spectrum availability 6-8 Since WRC 97, Aviation has lost its AMS(R)S (1.5 - 1.6 GHz) spectrum exclusive allocation (14 10 0 MHz bandwidth), However, ITU recognises aviation as priority users of the band pending on supporting services in the 1 - 6 priority levels (according to ITU definition) - ITU footnote S5.357A At Eurocontrols request, CEPT CPG confirmed that, when Aviation is ready to operate the service, Administrations will have to ensure access to the frequency in the former AMS(R)S sub-band.

47 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 AMS(R)S spectrum availability ITU WP 8D is looking at the feasibility of introducing priority/pre-emption of intra/inter systems (resolution 222) Such a mechanism is not felt feasible However, ITU did not define deadline for concluding the feasibility study work (WRC06, WRC09 ?) The ICAO position is to ask WRC03 to fix WRC06 as the target date to conclude and define relevant further action Aviation spectrum managers should be pro-active in supporting this position with their National Radio Regulators 6-9

48 One Sky for Europe EUROCONTROL © 2002 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 26 Nov 02 Ed 1.1 AMS(R)S spectrum availability Now there is a real opportunity for satellite-based communication systems to enhance air traffic management in Europe and the rest of world We have rights to access spectrum in the L-band but this needs to be protected 6-10
