1 Iris Annex (Prepared by the European Space Agency) V1.1, 1/10/2008 The task descriptions referring to the ESA Iris Programme are presented for the purpose of coordination and better understanding of interface requirements only. ESA will issue an Invitation To Tender (ITT) relative to these tasks in the first quarter 2009, subject to obtaining programme funding at the ESA Council at Ministerial Level in November The inclusion of these high level task descriptions in the present SJU Documentation does not prejudice ESA in modifying these tasks before issuing its ITT. Summary The Research and Development activities concerning a satellite based communication system as part of a dual (terrestrial plus space-based) Air/Ground Data Link has been included in the SESAR ATM Master Plan. The European Space Agency (ESA) has demonstrated the compliance of satellite communications to the Aviation requirements through it Satellite Data Link System (SDLS) project ( ) and its economic appeal through the Satcom for ATM Business Case study ( ). In parallel with the launch of the SESAR definition phase, ESA launched the Iris Programme, with the objectives to: On the basis of the SESAR requirements, develop a new satellite-based Air-Ground communication system for Air Traffic Management and to validate the end-to-end performance of a new satellite-based Air-Ground communication standard for Air Traffic Management. The new system shall allow the use of low-cost avionics and seamless transition between high-density continental areas and ORP. Subject to agreement with the SESAR JU/European Commission and a future Operating Entity, to develop a subset of the system for validation of this new satellite-based Air-Ground communication system for Air Traffic Management. The Phase 1 of the Iris programme, which comprises the industrial Phase A work, will be completed at the end of 2008 and provide inputs on feasibility scenarios and requirements. The Iris Phase 2.1, to be approved at the ESA Council of Ministers (26/11/2008) will cover the industrial Ph B, leading to a decision point in 2011 for the start of Phase 2.2 (industrial Ph. C/D/E1) including development of the communication system and deployment of the elements required for validation and initial operations. Depending on the option chosen by SESAR, the system to be deployed may require the design of a dedicated space segment or the adaptation as necessary of a planned one (entry into service is foreseen in the 2020 timeframe). The satellite-based communication system includes:

2 the communication protocols developed to support aviation communications (data and voice) whose specifications will be the subject of a Technical Manual to become an ICAO standard the ground segment: Ground Earth Station(s), Network Management Center, Network Control Centre and Gateway(s) to SWIM; the user terminal: low cost aircraft satcom avionics; the space segment: the communication payload and its specific satellite control station equipment; It is expected that no development is required for the satellite platform itself (the Bus) for which a number of COTS products exist. The operational infrastructure will be designed but is to be procured by the future owner(s). To support the end-to-end validation needed for the safety service, according to the SESAR validation requirements, the minimum system required will be derived from the design of the operational system. According to the option chosen, this pre-operational system, called the subset will be designed and procured, with the objective to start the on-orbit validation activities by mid The ESA validation activities are expected to last until mid-2015, after which the subset will be available for service validation, equipment certification and service roll-out. Once the design has been validated, this will allow for procurement, by the owner and before 2020, of the complete operational infrastructure. The operational infrastructure will be dimensioned to meet the SESAR safety and service availability requirements and provide sufficient capacity for the expected traffic. Hereunder is a high level description of the activities foreseen as part of the ESA Iris programme Phases B/C/D/E1. They are provided to support the coherence of the overall SESAR development phase DoW. The Iris effort identifies 5 main Work Packages, which will be the subject of a single ITT to be issued in the 1 st QTR of 2009 (pending funding approval at the 2008 Ministerial Conference): WP1 System WP2 Communication Standard WP3 User Terminal WP4 Space Segment WP5 Ground Segment
