5 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Item 3 - Overview of Satellite Communication Activities since the first meeting

6 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D World Radio Conference 2003 (1/2) Successful for aviation retention of spectrum global acceptance for Connexion on secondary basis Resolution to study, as a matter of urgency, the current satellite frequency allocations that could meet aeronautical requirements to support the modernisation of civil aviation telecommunication systems, especially those in developing countries, and to study in particular those radio frequencies that could be used to support both ICAO CNS/ATM systems and other non-aeronautical telecommunication services this could imply increased use of satellite communication systems

7 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D World Radio Conference 2003 (2/2) Resolution 803 to consider results of ITU-R studies in accordance with Resolution 222 (WRC-2000) to ensure spectrum availability and protection for the aeronautical mobile satellite (R) service, and to take appropriate action on this subject, while retaining the generic allocation for the mobile-satellite service Aviation needs to continue to ensure it has sufficient spectrum in the future in the L-band

8 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D ICAO 11th ANC 11th Air Navigation Conference (ANC) looked at all ICAO activity since the last ANC in 1991 many technical systems developed but not all implemented emphasis now on definition of operational concepts need for greater regional harmonisation need for more spectral efficient systems A number of Recommendations related to new technology including satellite communication were formulated.

9 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D ICAO 11th ANC Recommendation 7/4 Investigation of future technology alternatives for air-ground communication. ICAO to a) investigate new terrestrial and satellite-based technologies, on the basis of their potential for ICAO standardisation for aeronautical mobile communications use, taking into account the safety-critical standards of aviation and the associated cost issues; b) continue evolutionary development of existing standardized ICAO technologies with a view to increasing their efficiency and performance; and c) assess the needs for additional aeronautical spectrum to meet requirements for increased communications capacity and new applications, and assist States in securing appropriate additional allocations by the ITU.

10 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D ICAO 11th ANC Recommendation 7/5 Standardisation of aeronautical communication systems…..for new aeronautical communication systems, ICAO will: a) continue to monitor emerging communication systems technologies but undertake standardisation work only when the systems meet all of the following conditions: –see next slide

11 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D ICAO 11th ANC Conditions for standardisation 1) can meet current and emerging ICAO ATM requirements; 2) are technically proven and offer proven operational benefits; 3) are consistent with the requirements for safety; 4) are cost-beneficial; 5) can be implemented without prejudice to global harmonisation of the CNS/ATM systems; and 6) are consistent with the Global Air Navigation Plan for CNS/ATM Systems (Doc 9750)

12 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D ICAO 11th ANC Recommendation 7/5 continued b) include in Annex 10 provisions ensuring that the introduction of mandatory carriage of new equipment be based only on appropriate ICAO regional and inter-regional co-ordination; and c) further limit SARPs for complex aeronautical systems to broad, system-level, functional and performance requirements and better capitalise on the work of other standard-making organisations so as to reduce the complexity/size of technical provisions. The intention is that NexSAT fully complies with these Resolutions For more information see

25 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D ATS requirement ATS requirements have been derived from the EUROCONTROL study Operating Concept of the Mobile Aviation Communication Infrastructure Supporting ATM beyond nicknamed MACONDO Compilation of EUROCONTROL Strategies based on ICAO CNS/ATM concepts compatible with ATMCP concepts From the agreed concept of operations the communication requirements were identified independent of technology

26 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Overview of Macondo

27 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Macondo Two main work packages WP1 established the ATM context in Europe in the by review of Eurocontrol strategies e.g. ATM2000+ and Operational Concept Document differences with non-European regions were identified - all broadly similar WP2 defined requirements on future mobile communication infrastructure to accommodate operational communication needs arising from the ATM operational context. Both voice and data communications were considered including the required Quality of Service Results presented at a Stakeholder Workshop last year and agreed Documents available at

28 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Homogenous Zones Airspace was characterised in general terms by flight phases, shape/density of traffic, ATM application mix. Each HZ is a portion of airspace within which ATM operational needs in terms of communication are similar The airspace segmentation criteria are: Airspace Density/Traffic Shape Airspace Regime (Managed (MAS), Unmanaged (UMAS), Free Flight Airspace (FFAS)); COSEP status(On/Off).

42 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Data Requirements For each concept/airspace scenario I.e. Homogenous Zones the performance requirements have been tabulated See Mission Requirements document - Table 3- 5 page 12 Definition of column headings are in Appendix B - Page 21

43 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Outputs of the study for ATS The resulting requirements are applicable to ANY communications technology I.e. technology independent now there is a need to match satellite communications technology against operational requirements for existing technologies match technology based on demonstrated performance for new technologies these are targets which need to be achieved The aim for new satellite communications is to achieve the as much as possible AT AN ACCEPTABLE COST However the performance of new satellite systems is not fully defined yet

44 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D AOC requirements

45 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Confirmation of AOC requirement These seem difficult to determine - initial input based on IATA paper was felt to be very low Aircraft manufacturers have some concepts related to monitoring the airframe Airbus supplied initial information on future AOC requirements Airlines have some concepts for the future Input from airlines via IATA sought But the general feeling is that if the communications channel exists it will be used fully ! Is this a sensible design goal ?

46 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D AOC requirements Voice assumed to continue but decline ? Data Link Flight Operations - a few examples of safety and regularity of flight applications –ACARS type applications –future more graphical information exchange –Electronic flight bag, etc Are all the applications really safety and regularity of flight applications? Does this matter ?

47 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Summary of ATS requirements The Macondo values for requirements have been included in Mission Requirements for around now we have to match technology against requirements so far we do not know what a new satellite system can achieve indicative figures from SDLS demonstrator are encouraging and can meet many of the requirement in a trials environment Decision that air to air communications is not appropriate for satellite communications –strikethrough in requirements table New requirements in other regions of the world ?

48 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D NexSAT versus Requirements We are now trying to match technology against safety (ATS and AOC) requirements ATS requirements seem better known and appear modest but AOC requirements are unclear but feedback suggests they are going to grow significantly - no hard numbers NexSAT will be complementary to ground systems but which requirements will it meet ? Decision that air to air communication is not applicable to satellite communications Need performance information of a NexSAT service to complete the matching process - taking into account costs

49 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Discussion Party-line voice is a continuing issue - if voice is only for unusual situations. Is it necessary ? AOC requirements appear difficult to capture airframe manufacturers have plans related to the maintenance of airframe airlines have plans for their own purposes but may be sensitive –do they classify applications into AOC and AAC ? Do they care ? Global requirements are expected through ICAO ACP How do we capture longer term requirements ?

50 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Longer term requirements For a new system to be viable it has to have a reasonable life time e.g. 10 to 15 years This means considering to What will this timeframe look like ? ESA has launched a long term study that is hoping to help answer this question

51 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Item 5 - Technology Review

52 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Role of Eurocontrol Working with industry to enable them to understand CNS/ATM requirements to allow industry to develop products to meet the requirements Likely that the greatest demand may result from AOC use Industry has to be comfortable with the business needs Eurocontrol will help in understanding and assist co-ordination Mandatory carriage of new technology is rare - the business case for equipage has to be obvious. A good solution will sell itself !

53 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Operational Improvements NexSAT is just enabling technology to allow operation to continue with benefits - when the VHF channel becomes congested new communication systems will be needed to maintain ATS lower cost communications - communication costs could be similar to VHF-based systems greater coverage with lower infrastructure costs - could offer a communication service in areas with limited or no communication coverage

54 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Satellite coverage 3-15 Assumption NexSAT (NGSS) will use an existing satellite infrastructure

55 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Possible Data and Voice coverage in Europe

56 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Data link application are transparent VDL M2 AMSSNexSAT Aircraft ATN Router Ground ATN Router Applications Better performance Lower cost Greater coverage

57 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Voice communications Voice requirements will reduce in the future but will still be required Should be transparent to users similar operating for ATS with same interface and flexibility AOC should be also be supported

58 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Candidate technologies Existing AMSS (I.e. Aero H (and I)) are being used to support ATS and AOC applications in low density areas but are perceived as costly and low quality of service Other systems Inmarsat Aero systems Swift64, BGAN, etc Boeing Connexion Iridium - Globalstar A new system

59 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Inmarsat systems Aero H,I and L these are being used to offer ATS (and other services) in several regions of the world Swift64 introduced to make better use of Aero H infrastructure for non-safety applications e.g. passenger services BGAN high data rates (up to 432kb/s) but not designed for safety services All systems operate in AMSS L-band Global infrastructure in place now and will continue to be ?

60 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Boeing Connexion High -speed Internet in the sky Only targeted at non-safety communications I.e. AAC and APC Does not operate in protected frequency band although obtain global allocation at WRC03 on a secondary basis Trials/service underway several airlines e.g. Lufthansa, British Airways, SAS, All-Nippon Airways,…… Working Paper at ICAO ACP WG-C last week

61 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Iridium & Globalstar Iridium is being used by aviation for AAC and APC applications but also by FAA in Alaska General Dynamics presentation Globalstar avionic product available A product that complies with RTCA DO-262 (NGSS MOPS)

62 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D A new system ? From initial considerations it is believed that no existing system meets all the requirements A service that has to have high levels of availability, reliability and continuity required for safety and regularity of flight communications safety must be built into the design process it has to be a world-wide system Therefore do we need to design a new system ?

63 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Supporting safety communications What makes supporting aviation safety communications special ? based on agreed international standards operates in a privileged radio band - AMS(R)S safety requirements should drive the design process in ground and aircraft systems –e.g. avionics have appropriate level of certification agreed level of service from the satellite and communications service providers –likely to cost more

64 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Narrow or Wide band ATS requirements - assuming they are correct - seem to be meet by a modest throughput AOC requirements are unclear and could be determining factor Do we need to consider AAC and APC requirements ? Can one service support all users ? This was the design philosophy behind the current AMSS. What is your opinion ?

65 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D New or existing system? Benefits of a new system tailored to meet the requirements can have new features built in smaller aircraft terminals Disadvantage costly development will take a long time need to find a champion What is your opinion ?

66 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Item 6 - Roadmap for development and implementation

67 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Implementation timescale How is this phase funded ? Industrial consortium, Public body Inmarsat ? The service provider has to start rolling out the service but traffic may be low initially

68 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Discussion Do we agree that there are opportunities for a better satellite communication system? Should we investigate new Inmarsat products, Connexion, Iridium, Globalstar ? What would it take to make them acceptable for safety communications ? Can they be used now for some applications ? If a new system is needed the development time will be long so we need to start now must be linked to business and institutional aspects

69 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 30 October 2003 Ed 0.D Discussion Do we agree that there are opportunities for a better satellite communication system? If a new system is needed the development time will be long so we need to start now ! What is a typical industry approach to review of technology requirements ? What is necessary to start an industrial development ?
