4ADF 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
5Capability Construct
6SATCOM Cardinal Requirements The Ends
- Coverage
- Ongoing operational requirement for Two Ocean
Presence (Indian and Pacific) - ADFs Primary Operational Area (White Paper)
- Australian Coverage Area of 30E to 170W (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
7SATCOM Cardinal Requirements The Ends
8Current 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 Defences transportable
terminals out to 2016 to facilitate the
convergence on MILSATCOM (military spectrum and
systems) - Likewise, major changes to Defences anchoring
architecture to accommodate WGS, IS-22, TDMA, IW
9 Current Capability The Ways
- Control Segment
- Defined as platform (satellite) monitoring and
control (MC) or transmissions and payload MC - Platform (station keeping, sub-system health
monitoring) - Defence not directly involved in platform MC of
bus - WGS MC is through US MILSATCOM architecture.
- DPS and IS-22 MC is included in commercial
contracts - Payload (circuit configuration, traffic
monitoring) - Defence maintains MC 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
