Agenda
1) Future Aeronautical Communications – Key Assumptions
2) Future data links in the SESAR context
3) Terrestrial Data Links
• LDACS: SESAR project P15.2.4
• AEROMACS: SESAR project P15.2.7
3
Basic Assumptions (1/2)
• Future (2020+) system needs to support ATS and AOC end-to-end communications including air/ground and air/air
• In future operating concept data becomes the primary mode of communications
• In case of failure of data com, voice is unlikely to be able to sustain operations at the same capacity level. Therefore different data links may be needed to maintain capacity of operations
• In the future concept voice will remain available for emergency communications
4
Basic Assumptions (2/2)
• No single technology meets all requirements across all operational flight domains
• Future system will be a system of systems integrating existing communication systems (voice, VDL) as well as new communications systems to meet the operational requirements
(Airborne) Integration of technologies needs to be facilitated
• Future system should support digital voice in the long term, however in the short term the emphasis is to support data communications
• Appropriate spectrum allocations: AM(R)S and AMS(R)S

Projects P15.2.7 and 9.16: Overall Aim
Define, validate and demonstratea technical profile and architecture
for a new airport surface communication system (AeroMACS)based on 802.16e IEEE standard
by studying, developing, integrating and testingsystem prototypes
• Project 15.2.7 covers overall system aspects and ground component
• Project 9.16 covers airborne component
20
Project P15.2.7 scope
• Overall system functional and performance definition• Definition of a new specific profile• Development of validation plans and scenarios • Specification of test objectives and procedures• Specification and development of (prototype) ground segment• Analysis, simulations and test campaigns addressing
interoperability (multiple manufacturers) in laboratory and realairport environments
• Security and safety analysis• Coordination with standardization bodies (RTCA and
EUROCAE)
21
Project P9.16 scope
• System requirements and architecture definition for the airborneside
• Specification and development of airborne prototype for mainline aircraft
• Specification of test objectives and procedures for airborne side.• Integration of the airborne prototype in a representative mainline
aircraft environment• Testing in real environment (on airport, using a/c representative
platforms, and up to integration in a real flight test a/c), • Advanced studies (limited effort): MIMO studies, integrated
antennas, WiMAX evolutions (e.g. 802.16m)
