Inmarsats Next Generation satellites and SARPs
compliant communications

• Inmarsat-4 will support existing Aeronautical
  safety services
• Inmarsats 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

Inmarsats 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 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

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
• 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

NexSat HLMR and Satcom CONOPS

• 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?

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
