SDLS SLICE 3 OUTPUTS

WP1 : Experimentation report WP2 : Services Definition Document (Services and QoS) WP3 : Core Engineering Activities

Detailed Studies Outputs Access and Waveform : CDMA waveform baseline (synchronous vs.

asynchronous trade-off) - options on channel coding (based on Turbocodes) and modulations (/4 QPSK / TCM 8-PSK modulations) providing optimal spectral efficiency

Protocols : specific protocol designs to meet several QoS grades Interoperability analysis to allow easy integration on existing and

future avionics and ground aeronautical networks

System Level Outputs System concept justification file System functional specification

WP5 : Economical Analysis (service cost evaluation)

SDLS AND NEXSAT INITIATIVE

Results :

SDLS project provided the core technical material for NexSat Circular

SDLS project supported Eurocontrol initiative at ICAO level (AMCP/8)

Current work :

SDLS project supports NexSat Mission Requirement Definition

SDLS project develops promotion material available for NextSat

(brochure, video)

SDLS project provides initial economical analysis of the system operation



SDLS FUTURE

Next phase : build-up of an ESA programme to develop the core element of the future aeronautical satellite system
