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
Capability Construct
SATCOM Cardinal Requirements – The Ends
•
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

Current Capability – The Ways
•
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
•
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
