Iris Phases are aligned with SESAR schedule

Objectives of Iris Phase 1 Emphasis on: Preparation work to support the SESAR Master Plan Initiate development of the communication standard Initiate identification of the most efficient satcom system architecture Consider non-technical issues from the start: Business case Service provision and governance model ESA hand-over after development/deployment Validation and qualification with SESAR Support frequencies allocation Contribute to estimations of spectrum requirements (e.g. ITU WP4C) Phase A activities timing is aligned with SESAR ATM Master Plan release

Outcome of Iris Phase 1 studies Satellite Communication System studies Analysis & Design of Satellite System studies ICOS + Phoenix AVISAT + Samara Iris Phase A studies 1Q08 to 3Q08 ...011010 1001010.. Com. System Satellite System Preliminary Design Specifications Avionics Preliminary Design Preliminary Design Specifications Service provision + Business case model Outcome expected What is new/COTS? Antennas: where? how many? Target cost?... Which type of architecture? Dependability? Target cost?... Which types of protocols? Are COCR performances achievable? Link budget?... Who operates what? Who procures what? Financing scheme?...

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 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. 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 France Germany Ireland Italy Norway Portugal Spain 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 3Q08 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.
