World Radio Conference 2003 (1/2)
• Successful for aviation retention of spectrum global acceptance for Connexion on secondary basis
• Resolution 415 - 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

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

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.

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)

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

ATS requirement
• ATS requirements have been derived from the EUROCONTROL study ‘Operating Concept of the Mobile Aviation Communication
Infrastructure Supporting ATM beyond 2015’ - 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

Macondo• Two main work packages
WP1 established the ATM context in Europe in the 2010-2015 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

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).

Voice System Capacity
Hypothesis for voice communication traffic estimation
– In TMA all tactical comms. supported by PARTY-LINE service
– Communication profiles derived from French VOCALISE project
– (channel load 60% at 95% upper bound, average contact 11s)
– Capacity given in number of contacts per hour for the whole ECAC
– Aircraft traffic profile based on Macondo WP1 inputs (PIAC)
– Broadcast traffic not taken into account
– Provision for datalink backup : 5% of nominal load

Evolution Scenario Assumptions Hypothesis 2002 :
– Load of 10 contacts per hour per aircraft (Vocalise study)
– in the TMA 90% of the traffic is for tactical exchanges (Vocalise study)
Scenario 2010 :
– Same communication traffic in the TMA for tactical exchanges as in 2002 (communication growth linearly linked to traffic growth)
– 50% of 2002 traffic for Strategic and Information exchanges Scenario 2015 :
– 10% reduction of the tactical exchanges in the TMA
– Residual traffic for Strategic and Information exchanges (5%)

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

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

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 ?

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 ?

Summary of ATS requirements
• The Macondo values for requirements have been included in Mission Requirements for around 2015 + 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 ?

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

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 ?

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 2015+ to 2030 +
• What will this timeframe look like ? ESA has launched a long term study that is hoping to help answer
this question

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 !

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

• Should be transparent to users similar operating for ATS with same interface and flexibility AOC should be also be supported

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

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 ? Inmarsat presentation

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

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)

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 ?

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

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 ?

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 ?

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

Business Aspects
• A ‘new’ Satellite communications system could bring benefits to aviation if it was at an ‘acceptable cost’
• Need ‘buy-in’ form a range of Stakeholders airspace users ATS providers Communications Service providers Satellite Service providers Manufacturing Industry

Cost and benefits
• Traditional C-B analysis will be needed to give indicative figures but may not be sufficient ATSPs tend to use CBAs
• Need to identify other business drivers e.g. benefits to early equipage, better operational control, etc
• A range of business options Single or Multiple ATSPs contract directly with SSP Airlines contract directly with SSP ATSPs and Airlines directly with CSP CSP directly with SSP and offer service primarily to support
airline operation

Institutional Aspects
• A number of issues have been identified including - standardisation - ICAO, EUROCAE/RTCA, AEEC, etc AMS(R)S spectrum availability - guaranteed amount of spectrum
needed at the right time Service level agreements providers of satellite and communication
services - guarantees Arrangement between satellite service providers needed if
provided by several providers e.g. global and regional/spot Certification and approval
