objectives of iris phase 1
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

Preliminary Design Specifications

Service provision + Business case model

  • What is new/COTS?
  • Antennas: where? how many?
  • Target cost?...
  • Which type of architecture?
  • Dependability?
  • Target cost?...

Outcome expected

  • Which types of protocols?
  • Are COCR performances achievable?
  • Link budget?...
  • Who operates what?
  • Who procures what?
  • Financing scheme?...
communication system design activity
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
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: 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
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
  • 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.
