  3. Inmarsat-4 will support existing Aeronautical safety services Inmarsat’s Public Service Agreement (PSA) commitment to ICAO (and IMO) For the near term, data and voice safety services will operate via Inmarsat H/H+, I and L Enhanced capabilities using the new Inmarsat-4 Satellites and new terrestrial infrastructure Inmarsat’s Next Generation satellites and SARPs compliant communications Eurocontrol NexSat Steering Group - Brussels June 2004

  4. Referred to as Aero-BGAN (Broadband Global Area Network) working title Designed to operate in conjunction with existing safety services (voice and data) and Swift 64. Will provide data rates up to 432kbps per channel. Will provide both ‘Circuit Switched’ and “Always on” TCP/IP data. Supported through High, Intermediate and Low gain antennas. Also provides the opportunity for development of significantly smaller terminals, and leads to lower priced services. Working with 4 avionics manufacturers Inmarsat’s Next Generation satellites – new capabilities Eurocontrol NexSat Steering Group - Brussels June 2004

  5. Inmarsat-4Satellite • User Link :L Band • Global, Regional and Narrow spot beams • Feeder Link :C Band • Spacecraft Power :12 kW • Launch Mass :6 Tons • Solar Array Span :48 m • Prime Contractor: Astrium • Current planned Launch Dates: • F1 (64E Indian Ocean)– 4th Qtr 2004 • F2 (53W Atlantic Ocean)– 1st Half 2005 • F3 ground spare Eurocontrol NexSat Steering Group - Brussels June 2004

  6. Inmarsat-4 Satellite • Launch Vehicles: • ILS Atlas 5 • Sealaunch • Current planned BGAN Service commencement • Mid 2005 • Aero services expected 2006 Inmarsat 4 integration and environmental testing in Toulouse Eurocontrol NexSat Steering Group - Brussels June 2004

  8. BGAN – Two Networks in One Eurocontrol NexSat Steering Group - Brussels June 2004

  9. CS Domain Direct Dial Voice SIM Roaming Voice Mail Services Other UMTS Services CLI, Call divert, Conf. Calling etc. SMS (Two way) ISDN PS Domain DSL class internet access Static and Dynamic IP addressing Bandwidth on demand Two service classes: Basic IP Services- UMTS “Background /Interactive class”- Variable data rate Premium IP Services- Streaming- Guaranteed bit rate BGAN Services Eurocontrol NexSat Steering Group - Brussels June 2004

  10. The Aero/Maritime Evolution programme consists of: 1) Activity funded as part of BGAN Extension Development through to technology validation. Aeronautical Directional Maritime Omni (inc Aero) Multi-cast 50% funded by ESA / 50% by Inmarsat and partners BGAN Extension & Evolution Eurocontrol NexSat Steering Group - Brussels June 2004

  11. 2) Other activities outside the Extension project Commercialisation Business Support Systems Type Approval Distribution/Sales/Marketing Multi-user enhancements Maritime directional products Land mobile/vehicular products BGAN Extension & Evolution Eurocontrol NexSat Steering Group - Brussels June 2004

  12. Includes propagation studies, physical layer specifications, proof of concept technology, final Air Interface definition for all product types Additional BGAN X Mar & Aero Omni Aero Directional Multicast Mar Directional Land Vehicular Multi-User Product Evolution Service Evolution I4/BGAN Evolution Studies Eurocontrol NexSat Steering Group - Brussels June 2004

  13. Evolution of the expected Aero-BGAN system would be required for safety services support, which might imply Planning timeline for pre-operational trials of Aero-BGAN safety services circa. 2010 Beginning safety service requirements evaluation.Many questions, not least: Contingency? How to achieve priority and pre-emption? The effect of applying ESARRs NexSat as part of latter stages of LINK 2000+? Also CASCADE? ICAO view of digital voice versus circuit mode? Inmarsat has made Aero-BGAN technical input to ICAO ACP WGC Aero-BGAN & Safety Services Eurocontrol NexSat Steering Group - Brussels June 2004

  14. NexSat HMLR provides good starting point for baseline requirements, but ideally A Concept of Operations is required for combined data and voice satcom operation in European region answering such questions as: What is the voice distribution requirement? Digitised voice offers new concepts of operation, should these taken into account? Which datalink services will the NexSat support? NexSat HLMR and Satcom CONOPS Eurocontrol NexSat Steering Group - Brussels June 2004

  15. ‘Make before break’ capability Seamless voice and data in designated areas Continuity of data delivery ‘Always-on’ capability removes previous inherent R, and T channel utilisation issues Digitised voice offering New ways to ensure ‘priority and pre-emption’ service Multicast capability Net radio Potential features enabling new Safety Services Eurocontrol NexSat Steering Group - Brussels June 2004
