Iris Phases are aligned with SESAR schedule

Objectives of Iris Phase 1 Emphasis on: Ø Preparation work to support the SESAR Master Plan o Initiate development of the communication standard o Initiate identification of the most efficient satcom system architecture Ø Consider non-technical issues from the start: o Business case o Service provision and governance model o ESA hand-over after development/deployment o Validation and qualification with SESAR Ø Support frequencies allocation o Contribute to estimations of spectrum requirements (e. g. ITU WP 4 C) Phase A activities timing is aligned with SESAR ATM Master Plan release

Communication System Design activity The activity includes: • Trade-off of existing and possible new standards • Analysis and consolidation of user requirement as documented by SESAR • Communication architecture design • Interfaces with SESAR terrestrial network • Definition of aircraft avionics • Design of associated hardware and software, development, validation and qualification procedures. • Software simulator for validation • Preparation of ICAO standardisation and certification activities Ø Preparation of ICAO standard (technical basis to support update of performance-based SARPS and preparation of a Manual)

Analysis and Definition of Satellite System The activity includes: • Analysis and consolidation of user requirements as documented by SESAR, and needs for possible ancillary services (to support business case) • All trade-offs on architecture, payload, platform, ground segment, deployment and operations schemes and provision of possible ancillary services, starting from existing/projected satcom infrastructure: Iris is NOT designing new satellites • Assessment of the business case for the provision of services • Preliminary analysis of integration of Satcom into SESAR’s overall infrastructure (SESAR task in the future). • Certification issues regarding the operators and operation of the satellite system • Definition of the operational responsibilities and liabilities in the service provision scheme. Ø Prepare all elements to define the satellite service provision

Iris Programme: Participating States and users’ involvement Iris programme Phase 1 funding has been secured by 10 Participating States (among ESA 17 Member States) Austria Norway France Portugal Germany Spain Ireland Italy Switzerland UK Iris Expert Group: users’ voice in the Programme Core members: DSNA, DFS, NATS, LFV, Nav Portugal, Avinor, HCAA, Iberia, IATA, Eurocontrol, EASA + invitees on specific topics (e. g. SITA, ARINC, Business Airlines, Low Fare Airlines, Helicopter Association, Inmarsat. . . )

Next steps § A dynamic has been created, fostering collaboration between industry, experts and R&D entities of both space and aeronautics background § Results of Phase A studies will be available from 3 Q 08 § The next milestone is ESA Ministerial Conference in November 2008 which will fund Phase 2 activities

Conclusions § Following WG-T recommended actions, ESA is developing a set of technical options for a new Satcom open standard that will be proposed for discussion with international parties and brought to ICAO once the technical design is sufficiently mature § Definition of this new communication system starts from the aircraft avionics side (i. e. the cost multiplier) rather than from the satellite side. § An effort is being made to minimise the operational and equipment costs, and especially to make sure that the equipment can be supplied and operated worldwide. § ESA mandate is to support the adoption of new satellite solutions where justified for the benefit of society. ‘Justified’ means a solid cost/benefits case, not technology for the sake of technology. The Iris programme is not about developing new satellites. § Through cooperation with Eurocontrol and SESAR, ESA will aim to obtain wide international support for standardisation of this new satellite communication system.
