  1. Chief Information Officer Group Australian Defence Force Satellite Communications Captain Vaughn Rixon, RAN – Director ICT Capability Coordination

  2. Scope ADF SATCOM Roles ADF Use of SATCOM SATCOM Capability Construct SATCOM Capability – Today SATCOM Capability – Tomorrow Future Challenges

  3. ADF SATCOM Broad Roles CIOG = Chief Information Officer Group CDG = Capability Development Group DMO = Defence Materiel Organisation Services = Navy, Air Force and Army

  4. ADF Use of SATCOM Operational Environment Characterised by concurrent operations, in dispersed locations, with a requirement for extension of Defence networks/voice services from the strategic environment into the operational and tactical domains SATCOM provides independent communications means Operations can not rely solely on terrestrial connectivity – may be compromised or not available Users may not be within line-of-sight, or in terrain constrained environment (urban, mountainous regions) SATCOM can achieve long distance connectivity (trunking) and netted communications Accordingly, cardinal requirements of coverage, capacity and connectivity endure

  5. Capability Construct

  6. Coverage Ongoing operational requirement for ‘Two Ocean Presence’ (Indian and Pacific) ADF’s Primary Operational Area (White Paper) Australian Coverage Area of 30°E to 170°W (WGS MOU) Contingency requirement for Rest of World coverage Capacity Increasing demand for bandwidth (new capabilities being introduced) New platforms, high data rate ISR streams, increased demand at HQ Current predictions suggest capacity requirements can be met; however, regular Information Exchange Requirements (IER) analysis is essential. Connectivity Extending strategic information networks into the operational arena Increasing use of coalition networks Growing need for netted communications SATCOM Cardinal Requirements – The Ends

  8. Space Segment Need for wideband and narrowband SATCOM remains extant Wideband primarily for long-haul communications supporting larger semi-static formations Narrowband primarily for mobile, tactical users with strategic and netted links Expect increased mobile wideband access as small wideband dishes are introduced Aim to converge on military systems and spectrum (WGS / DPS / IS-22) Commercial SATCOM will continue to be required for alternate means, surge or where military spectrum can not be used Terminal Segment Classified as either platform-based, transportable or anchor terminals Platform-based are the responsibility of the project introducing the major capability Significant change to Defence’s transportable terminals out to 2016 to facilitate the convergence on MILSATCOM (military spectrum and systems) Likewise, major changes to Defence’s anchoring architecture to accommodate WGS, IS-22, TDMA, IW Current Capability – The Ways

  9. Control Segment Defined as platform (satellite) monitoring and control (M&C) or transmissions and payload M&C Platform (station keeping, sub-system health monitoring) Defence not directly involved in platform M&C of bus WGS M&C is through US MILSATCOM architecture. DPS and IS-22 M&C is included in commercial contracts Payload (circuit configuration, traffic monitoring) Defence maintains M&C on DPS WGS influenced through close liaison with all agencies in the US architecture IS-22 and others through coordination with the commercial provider Network Segment Provides the interfaces to the strategic networks and connectivity between anchor and control sites The most significant change to the network segment in the near future will be convergence on IP switching Current Capability – The Ways

  12. Future Challenges Enhanced UHF SATCOM Capability (JP2008 PH5A and AUS/US UHF MOU) AT&E/OT&E Coordinating change to control segment Combined operations with US Changes to Australian Wideband anchoring Interim anchoring (WGS) SGS(W) SGS(E) Introduction of new SATCOM terminals and platforms New technologies (IW, TDMA, IP) New capabilities – Protected SATCOM, DTCS, L-Band TACSAT Maintaining GEO orbit slots (IOR and POR) Sustaining the SATCOM Capability (WGS follow-on)
