Need for a complementary system
The Aeronautical Mobile Communication Infrastructure needs to evolve to: Accommodate Traffic growth Need for additional
capacity outside the VHF band saturation anticipated in Europe even with new VHF technologies
Accommodate new ATS functions increasing flight safety, security and efficiency. These data exchanges will increasingly complement voice communication, which will still be required for immediate emergency and non-routine exchanges.

Satellite communication technology
Among the candidate systems, satellite-based technologies are being considered due to: their ability to offer near-global coverage
they can be used where it is difficult or costly to implement a ground infrastructure
spot or regional beams can offer greater capacity where needed (e.g. in high density airspace)
they are suited to air-ground communications and broadcast applications
their capability to complement terrestrial systems (thus reducing pressure on the VHF spectrum)

From concept to implementation

Current AMSS
The current AMSS meets its design goals by -
offering safety and non-safety services to a full range of users sharing the L-band spectrum
However, there is limited deployment due to -
The cost of aircraft installation and avionics
The need to use Large Ground Earth Stations (GES) leading to limited options for communications service provision
Therefore currently AMSS is being used only in low-density and oceanic type airspace
New generation satellite communication systems could offer a higher quality of communication service for use in both low and high density airspace

Required Communications Services
High levels of availability, reliability and continuity required for safety and regularity of flight communications ATS Service
Voice - generally decreasing in use
Data - generally increasing in use
needs to support future ATM operational concepts from ICAO ATMCP in each type of airspace
AOC Service Voice - meet continuing need for voice communications
Data - support increasing exchange of data messages

*Eurocontrol Report ‘Operating Concept for the future mobile communication infrastructure - D2’
Capacity Requirements
ATM concepts seem to need modest instantaneous throughputs - can be met by a medium rate highly reliable communication system (approx. ~1 kb/s* for data exchanges on average)
Flexibility to increase the communications capacity in specific high density areas through use of regional or spot beams
AOC voice requirements are still being considered but airlines foresee a large increase in data communications

Reuse and improve
A good infrastructure has been built up so let’s re-use it
GEO Satellites
GESs
Spectrum in L-band
Terrestrial networks
Institutional arrangements
but improve on it by overlaying it with a system with new features.

New Generation Satellite System
Some possible new features - Low cost avionics
Use of advanced access and modulation techniques
Option to use Ku-band feeder links enabling small GESs
Design in high levels of availability, reliability and continuity required for safety and regularity of flight communications
These features are being investigated in the ESA Satellite Data Link System (SDLS), a project demonstrating the capabilities of satellite com system and investigating issues

ESA Satellite Data Link System
The ESA SDLS project has been underway for several years
Key features of SDLS include design to meet to safety and regularity of flight communications
Code Division Multiple Access e.g. to allow multiple access and increase overall efficiency
Ku feeder link
Party-line voice service
support for repetitive short messages
A demonstrator has been developed by Alcatel Space in Toulouse

Other technologies
Existing AMSS (i.e. Aero H and I) are being used today for safety and regularity of communication applications (ATS and AOC) and also for non-safety airline administrative (AAC) and passenger communications (AAC and APC)
Other satellite communication systems that are also being used or are planned include: Inmarsat aeronautical systems - Swift64, BGAN

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

Service was designed to offer a high-speed Internet in the sky
Only targeted at non-safety communications I.e. passenger (APC) and non-safety related airline use (AAC)
Does not operate in ‘protected’ frequency band obtained a global allocation at WRC03 on a secondary basis
Trials/service underway by several airlines e.g. Lufthansa, British Airways, SAS, All-Nippon Airways,……

Iridium
Iridium offers a truly global coverage with 66 Low Earth Orbiting (LEO) satellites
Iridium is being used by aviation mainly for non-safety applications e.g. AAC and APC
However the FAA is planning to use Iridium to augment its terrestrial UAT network in its Capstone project in Alaska
Iridium offers a voice and data service

Business Aspects
A ‘new’ Satellite communications system could bring benefits to aviation but it has to be at an ‘acceptable cost’
Need ‘buy-in’ from a range of Stakeholders airspace users
ATS providers
Communications Service providers
Satellite Service providers

Cost and benefits
Traditional C-B analysis will be needed to give indicative figures but may not be sufficient
Need to identify additional business drivers e.g. benefits of early equipage, better operational control, marketing benefits, etc
A range of business options
Single or Multiple ATSPs contract directly with SSP
Airlines contract directly with SSP
ATSPs and Airlines contract directly with CSP
CSP contract 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 with providers of satellite and communication services
Arrangement between satellite service providers needed if provided by several providers e.g. global and regional spots
Certification and approval

Spectrum availability (1/2)
The currently AMS(R)S operates in the L-band (1.5 / 1.6 GHz) where aviation is a privileged user Radio Regulations give AMS(R)S priority in use of spectrum
The amount of AMS(R)S spectrum needed is dependent on applications (ATS - Voice & Data; AOC Voice & Data)
The L-band is attractive for all mobile communication propagation characteristics

EUROCONTROL‘One Sky for Europe’
Spectrum availability (2/2)
Important considerations more non-safety related communications could put
pressure on safety users
obtaining a world-wide AMS(R)S allocation and deploying systems globally may take some time
important for aviation to use the spectrum

Next steps
We are finalising the Mission Requirements for the NexSAT service take into account European AND other region
requirements
contributing to the ICAO activity through the Aeronautical Communications Panel
we need inputs from all ICAO regions on future ATS requirements
future airline operational control communications requirements
input is invited from this region - see Eurocontrol NexSAT web page for contact details

Summary
Satellite communication systems are already providing benefits to airspace users and ATSPs in several areas of the world - usually low density oceanic
New satellite systems could have better performance which may be used to support ATM in higher density airspace such as Europe and in other regions of the world
Spectrum to support new safety-related applications of satellite communications must be protected
EUROCONTROL is refining the requirements and will match these to emerging technologies
Co-ordination and involvement with all regions of the world is vital to achieve a globally harmonised system
