4 Objectives of Iris Phase 1 Emphasis on:Preparation work to support the SESAR Master PlanInitiate development of the communication standardInitiate identification of the most efficient satcom system architectureConsider non-technical issues from the start:Business caseService provision and governance modelESA hand-over after development/deploymentValidation and qualification with SESARSupport frequencies allocationContribute to estimations of spectrum requirements (e.g. ITU WP4C)Phase A activities timing is aligned with SESAR ATM Master Plan release

6 Communication System Design activity The activity includes:Trade-off of existing and possible new standardsAnalysis and consolidation of user requirement as documented by SESARCommunication architecture designInterfaces with SESAR terrestrial networkDefinition of aircraft avionicsDesign of associated hardware and software, development, validation and qualification procedures.Software simulator for validationPreparation of ICAO standardisation and certification activitiesPreparation of ICAO standard (technical basis to support update of performance-based SARPS and preparation of a Manual)
7 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 satellitesAssessment of the business case for the provision of servicesPreliminary 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 systemDefinition of the operational responsibilities and liabilities in the service provision scheme.Prepare all elements to define the satellite service provision
8 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 France Germany Ireland ItalyNorway Portugal Spain Switzerland UKIris Expert Group: users’ voice in the ProgrammeCore 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...)
9 Next stepsA dynamic has been created, fostering collaboration between industry, experts and R&D entities of both space and aeronautics backgroundResults of Phase A studies will be available from 3Q08The next milestone is ESA Ministerial Conference in November 2008 which will fund Phase 2 activities
10 ConclusionsFollowing 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 matureDefinition 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.
