Inmarsat’s Next Generation satellites and SARPs compliant communications – 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 Eurocontrol Nex. Sat Steering Group - Brussels June 2004

Inmarsat’s Next Generation satellites – new capabilities – 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 432 kbps 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 Eurocontrol Nex.

BGAN – Two Networks in One Eurocontrol Nex. Sat Steering Group - Brussels June 2004

BGAN Services • 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 • CS Domain – – Direct Dial Voice SIM Roaming Voice Mail Services Other UMTS Services • CLI, Call divert, Conf. Calling etc. – SMS (Two way) – ISDN Eurocontrol Nex. Sat Steering Group - Brussels June 2004

BGAN Extension & Evolution • 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 Eurocontrol Nex. Sat Steering Group - Brussels June 2004

BGAN Extension & Evolution 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 Eurocontrol Nex. Sat Steering Group - Brussels June 2004

I 4/BGAN Evolution Studies Includes propagation studies, physical layer specifications, proof of concept technology, final Air Interface definition for all product types Additional BGAN X Product Evolution Mar & Aero Omni Aero Directional Mar Directional Land Vehicular Service Evolution Multicast Multi-User Eurocontrol Nex.

Aero-BGAN & Safety Services • 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 Nex. Sat 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 Eurocontrol Nex. Sat Steering Group - Brussels June 2004

Nex. Sat HLMR and Satcom CONOPS • Nex. Sat 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 Nex. Sat support? Eurocontrol Nex. Sat Steering Group - Brussels June 2004

Potential features enabling new Safety Services • ‘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 Eurocontrol Nex.
