6 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Item 3 - Overview of Satellite Communication Activities since the first meeting

7 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Primary driver in Europe is communication spectrum Need to find solutions that operate outside the VHF band The problem is here already but is predicted to become critical around satellite communications systems offer the capability to complement terrestrial systems Satellite systems are available or being developed review the potential of these systems contribute to definition of the requirements of evolving systems Why satellite systems ?

8 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Initial Technical Specification Initial technical specification of a potential new system - NexSAT - developed drawing on - early ESA MSBN work SDLS demonstrator + new ideas First draft sent to Steering Group members just before Christmas - thanks for comments Final document input to ICAO AMCP/8 Thales Aviation UK study proved there were no show stoppers with some basic concepts

9 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Initial Technical Specification The document contains a combination of technical standards, guidance material and circular material. Some of the sections are very similar to those in the existing AMSS SARPS because NexSAT supports the same services packet data voice Although there is a considerable amount of information in the document it is still open for discussion and refinement

10 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Avionic considerations A key to the use of a new system is the impact on aircraft largest investment therefore minimise unit cost problems of retrofit achievable technical performance versus size and cost Study undertaken by a leading satellite avionic manufacturer to review and comment on assumptions Thales Avionics study (WP2) looked at trade-off in power, costs, antenna gain, and other implementation issues

11 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Thales Avionics presentation

20 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Conclusions There is a lot of activity underway on satellite communications work restarted in ICAO work underway in the Europe, Japan, US and other places Different technical options for the communication system some available now - some not designed for safety communications other long-term solutions being designed for safety communications

21 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Item 4 - Recall of Operational Requirements

22 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D High level global requirements What are the basic requirements for a system operating worldwide - Defined in ICAO standards and Technical Manual Supports Safety and Regularity of flight communications only i.e. AMS(R) S Operates in L-band and uses it efficiently (bits/Hz) Supports voice and data simultaneously Interface to the ATN Offers global coverage and regional coverage Operation of the system is transparent to the end users

23 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Mission of the system for Europe (1/2) Offers communication service in controlled airspace Initially in upper airspace only core and non-core area Later in all controlled airspace for data but not TMA or airports for voice Interface to ATN and IP networks Interface to ATS voice network and to PSTN for AOC ATS Voice broadcast to all or group of aircraft ?

24 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Availability figures compatible with Macondo Multi-user service availability Meets Peak Instantaneous Aircraft Count (PIAC) expected in ECAC around 2015 i.e. around 2000 in upper airspace in all ECAC Provides party-line voice service to offer seamless transition between VHF and satellite areas No requirements for a high rate position reporting Aircraft to aircraft communications are not supported Mission of the system for Europe (2/2)

25 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D European Implementation assumptions (1/2) Start with existing global infrastructure Able to add European regional beam(s) as required AES costs minimised to around typical VHF radio values GA not generally expected to be equipped unless in controlled airspace Certification of avionics to Level C No specific security provisions in the subnetwork Possibility to use of small Ku band GESs at a number of locations in Europe

26 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D European Implementation assumptions (2/2) Satellite and GES diversity where possible to achieve very high reliability and availability (designed in system but implemented as required) Subnetwork specific protocol for short data messages

27 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D STNA - Mission Requirements Luc Deneufchâtel

28 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Some Technical Assumptions Use of CDMA Low rate vocoders (4.8 or 2.4Kbps) Throughput requirements compatible with Eurocontrol MACONDO study for ATM applications AOC throughput requirements for data link applications are as described in ICAO AMCP working paper

29 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D ATS QoS requirements Most demanding data requirements from Macondo study Aggregated throughput requirements around 1200 bps per aircraft excluding ADS-B

30 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D ATS Voice Extract from MACONDO study

31 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D AOC Applications Voice assumed to be continued to be required although expected to decline - requirements are considered as non-demanding Data Link Used extensively today Use will grow over time Requirements are difficult to determine Information presented at AMCP Aggregated throughput requirements for current and future applications - 52bps en-route (22 bps at the gate)

32 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D AOC data link applications Current Applications Out Off On In (OOOI) NOTAM Request/NOTAMS Free Text Weather Request/Weather Position Weather Report Flight Status Fuel Status Engine Performance Reports Maintenance Items Flight Plan Request/Flight Plan Data Loadsheet Request/LoadSheet Transfer Flight Log Transfer Future Applications Real Time Maintenance Information Graphical Weather Information Online Technical Trouble Shooting Real Time Weather Reports for Met Office Telemedicine Technical Log Book Update Cabin Log Book Transfer Update Electronic Library Software Loading

33 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Conclusion Therefore the conclusion appears to be that for safety related communications only a low throughput solution is needed for data The requirements for voice are in upper airspace which is more strategic. Low rate vocoder is likely to satisfy requirements (to be confirmed) Therefore overall data rates are low at around 4-8 kbps

34 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Discussion Are the assumptions on ATS and AOC requirements correct ? Is data and voice required simultaneously ? Is position reporting required ? Are ATS voice communications with the same level of service to VHF R/T required ? Do we attempt to make the use of satellite transparent to the controller What are the HMI issues in setting up the channel

35 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Item 5 - Roadmap for Development

36 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D History of satellite communications for aviation Dedicated aviation satellite in 1970s - AEROSAT - failed In 1980s PRODAT experiments showed satellite supporting ATM Inmarsat changed convention to support other forms of mobile satellite communications including aeronautical supported by their signatories ICAO FANS mainly driven by promised of satellite technology industry sensed market opportunities airline carried out market surveys - main revenue from passengers to fund equipage

37 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D History of satellite communications for aviation INMARSAT acted as the focal point for definition of the system - System Definition Manual Support of the ICAO process liaison with industry, communication service providers and airlines definition of enhancements to space segment to support safety communications - safety studies safety communications was recognised as important area network operations for Inmarsat satellites

38 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D The current AMSS was born Design choices for the current ICAO AMSS based on a business case for sharing of safety and non-safety traffic and shared use of spectrum Designed to meet full range of users Large aircraft installation and avionics for long haul aircraft Use of Large Ground Earth Stations (GES) operated by PTT-type organisations Compatible with as Inmarsat Aero H and H+

39 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Inmarsat Aero H Currently deployed in around 3000 aircraft - mainly long haul Some of these are FANS1/A equipped for ATM use in various regions of the world - mainly remote or oceanic Operational applications and meet by the performance of the system in these types of airspace Performance is not adequate for high density high space Aero I introduced with cheaper antenna for service in spot beam - few deployed Aero L low cost data only - deployed for helicopter safety

40 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Other Candidate technologies Aero H (and I) perceived as costly so can we use other systems at exist or are emerging ? Boeing Connexion Iridium Globalstar Inmarsat Aero systems Swift64, C, Mini-Aero, ………. Or another system as an evolution of AMSS ? NexSAT

41 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Other Inmarsat systems No other systems are defined in ICAO SARPs …? Do they meet the requirements ? Store and forward type systems do not - non-deterministic delivery times Swift64 could meet requirements but not offered for safety related communications (position could change) Will future Inmarsat systems support safety communications ?

42 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 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 Trials with Lufthansa and British Airways for passengers only

43 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Iridium & Globalstar Iridium is being used by aviation for AAC and APC applications but also by FAA in Alaska Globalstar avionic product available A product that complies with RTCA DO-262 (NGSS MOPS) Both primarily aimed at GA and for non-ATS related uses Can they be used for safety related communications in Europe ? Frequency bands - they are not able to offer AMS(R)S What is the guaranteed length of service ? What performance is guaranteed ? Number of users ?

44 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D So what are the options ? Iridium and Globalstar do not appear to be candidates doubts over their long-term viability shared with non-safety services not defined in ICAO standards (at the moment anyway) Inmarsat Swift64, C and Mini-Aero not designed to support safety communications not designed for safety services not defined in ICAO standards (at the moment anyway) Improve the existing Aero H system possible but difficult

45 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D NexSAT - a new design ? No existing system seems to meet the requirements so can we design and implement a new system ? Design 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 - Safety Regulation Unit has some ideas on how to do this A world-wide system But it does not exist yet

46 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D How can we implement NexSAT ? Difficult but not impossible Impossible is nothing but an excuse for the weak and a challenge for the bold For safety communications Inmarsat are unlikely to act as they did in the past We need a champion how will act in a similar way

47 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Reuse and improve Aviation is unlikely to be able to afford its own satellite system reuse existing infrastructure where possible GEO Satellites GESs Spectrum in L-band Terrestrial networks Institutional arrangements add regional beams

48 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Example European regional beam ARTEMIS 3-15

49 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Role of a Champion Need to have a long term vision Can see the commercial potential Willing to invest in the considerable development process Willing to co-ordinate the various interests avionic, space segment, communication service provision, etc Is willing to market the system

50 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 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

51 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D STNA Study on Institutional Aspects Luc Deneufchâtel

52 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Discussion How will the considerable R&D funding be found ? How will non-European interests be included ? ICAO for the technical standards but what about operational (mission) requirements ? When does the R&D phase finish and the implementation phase begin ? To meet the timescale we need to start now ! …….

53 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Item 7 - Discussion of future activities

54 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Discussion of future activities Eurocontrol has identified 3 main areas in which some further detailed work may be required business model institutional aspects mapping operational requirements to physical airspace Detailed descriptions of work necessary to clarify these areas are being prepared 7-1

55 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D 1 - Business aspects (1/2) 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 Cost benefit studies have to be carried out identification of benefits including do nothing option comparison of technology solutions to achieve same result view point models to be defined communication cost confirm goal of making equipment costs significantly lower than AMSS 6-4

56 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Business aspects (2/2) What are the cost saving for ATSP/airlines ? Do nothing case alternative solutions Satellite capacity is expected to be leased from space segment provider - who pays for this ? Could it be paid on behalf of the European aeronautical community by a communication service provider and recovered based on usage by ATS or AOC flexible service provision mechanisms Funding development and deployment 6-4

57 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Institutional issues Standardisation ICAO, RTCA/EUROCAE, ETSI, AEEC standards also detailed technical standards for the system Role of communication service providers (e.g. ARINC, SITA) Space segment providers co-ordination between them in sharing common resources (assignment of frequency sub-bands and possibly of codes (in CDMA system) to the various access points (GESs))

58 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D ICAO Institutional Criteria (1/2) Comply with the Radio Regulations of ITU and benefits from Radio Regulation protections for AMS(R)S Ensure priority, precedence and pre-emption for AMS(R)S consistent with AMSS SARPs requirement Supplies AMS(R)S service on non-discriminatory basis to all ATS/AOC organizations Commits to long-term provision of AMS(R)S Commits to the backward compatibilty of future technology transitions Demonstrated commitment of service/system provider and avionics supplier(s) to international and national standards development and approval process

59 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D ICAO Institutional Criteria (2/2) Provides necessary documentation to regulatory and user community Provides non-discriminatory access to necessary communications technology Provide near global coverage Provides security against unauthorized activities and communications Unrestricted access for distress/urgency communications Provides details on the design and documentation standards followed in designing the NGSSs

60 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D 3 - Supporting real world requirements Mobile Operating Concept study was useful in defining types of information exchange HZ do not map easily into physical airspace this is needed to identify physical implementation choices e.g. size and position of satellite beams QoS is dependent on position of aircraft in beam degrades towards edge of coverage If voice communications is it supported on a sector basis ? many sectors in Europe expanded

61 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D

62 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Mapping applications to airspace Eurocontrol study has categorised airspace as a set of Homogeneous Zones In each HZ, mobile communications (voice and data) will be required with varying qualities of service. High density airspace has highest QoS Not all data link or voice services will be supportable by satcom Need to map QoS to system design/cost and capability there still has to be an iterative between mission objectives, system design, achievable performance, safety and costs

63 One Sky for Europe EUROCONTROL © 2003 European Organisation for the Safety of Air Navigation (EUROCONTROL) NexSAT NexSAT Steering Group Meeting - 20 May 03 Ed 0.D Design cycle System design Performance Safety Cost Operational requirements
