PINE GAP
Pine Gap, officially known as the Joint Defence Space Research Facility,
is one of the largest and most important US satellite ground control
stations in the world.
Established in 1968 as a CIA intelligence base and situated in Central
Australia, 19 km south-west of Alice Springs, it consists of a large
computer complex with eight radomes protecting its antennae from the
elements and satellite reconnaissance.
In the 1960s, there was much technical expansion of electronic communications
in space. Satellites equipped with powerful receivers were strategically
positioned to eavesdrop on selected communications. The satellites
act as giant microphones which can accurately pick up even minor transmissions
and rebroadcast them to receiving stations (such as Pine Gap) on earth,
which then process or redirect the signals.
The first generation of satellites, launched in 1970 the year Pine
Gap became operational, were designed to spy on Soviet missile developments
and for general espionage in Asia. They were used during the 1971
Indo-Pakistan war, in Vietnam, and later to spy on China.
A second generation was launched in the mid-1970s, especially designed
for communications surveillance -- for example, conversations and
radio communications between Soviet military commanders.
The development of third generation satellites, launched in 1978,
was stepped-up after the 1979 fall of the Shah forced the closure
of US eavesdropping bases in Iran.
A fourth generation, Magnum, was launched on the space shuttle Discovery
in January 1985. These were huge receivers designed to pick up information
on Soviet missile tests, and military and diplomatic communications.
From 1983, Pine Gap was expanded to receive the increased volume of
signals from these satellites.
Pine Gap's most important role is processing information gathered
by Rhyolite signals intelligence (SIGINT) satellites and transmitting
that information to the United States. These satellites act as 'vacuum
cleaners', sucking up radio transmissions across a wide spectrum.
Military intelligence is obtained, along with economic, political
and domestic information from national and international telephone
and radio communications between allies and enemies alike.
Pine Gap's satellites gather military radio transmissions, giving
information on military readiness, troop and ship movements and other
matters. The satellites can intercept radar emanations, allowing mapping
of air defences, anti-ballistic missile radars and early-warning radars.
During the Gulf War, Pine Gap intercepted electronic and radio signals
from the Iraqi forces, providing vital intelligence for US Army commanders
in the Gulf. The base played a significant role in providing information
on Iraqi air and ground defences, troop deployments and military infrastructure
- the information supplied through Pine Gap helped to make possible
the final American assault on Iraqi forces.
Warheads released by ballistic missiles during test flights emit telemetry
(radio signals) which provide Pine Gap with information on missile
performance. The technical characteristics of the missile can be determined
to verify the Strategic Arms Limitations Talks (SALT) agreements.
It is often argued that the bases are needed in the post-Cold War
period for arms control verification - even though NMD will destroy
the existing arms control regime. However, Pine Gap's arms treaty
verification role is estimated to be as little as 0.3% of its activity.
NURRUNGAR
The US facility at Nurrungar, 500 km north-west of Adelaide, was established
in 1971 as a US military communications base.
Its main role was to monitor nuclear explosions and missile launch
activity and convey the information to the US. It was the main overseas
station for the US Defence Support Program (DSP). These functions
have now been transferred to Pine Gap.
Nurrungar received data from Defence Support Program (DSP) satellites
which monitor missile launches and nuclear explosions and relayed
this information to the United States.
The Defense Support Program is a vital element in the US military's
worldwide network. DSP consists of satellites and two main ground
stations: one in Colorado (USA) and the other at Nurrungar.
The DSP satellites have infrared sensors which detect the hot exhaust
plumes of missiles in their boost phase just after launching. Thus
the satellites can provide early warning of a missile attack and also
pinpoint the location of the launch sites.
Information on where, when and how many missiles are launches is vital
to any war-fighting strategy. DSP satellites also carry NUDET (NUclear
explosion DETection) sensors which can detect nuclear explosions in
the atmosphere and provide information on their location and density.
Nurrungar was the command and control station for DSP-East - the satellites
located over the Indian Ocean to detect missile launches and nuclear
explosions in Europe, Africa, the Middle East, the states of the former
Soviet Union and Asia.
Between June 1989 and February 1991, the US launched three of a new
generation of DSP satellites known as DSP-14. Equipped with advanced
NUDET sensors and 4,000 more infrared sensors, the new satellites
allow better discrimination between missiles of different countries
and can provide instant warning of their launch and location.
The ALP has said that in Government it will "very carefully review
the issue of possible Australian involvement in the NMD program through
the role of the Satellite Relay Ground Station".
This is the same as saying it is prepared to support NMD since the
Satellite Relay Ground Station at Pine Gap replaces the US base at
Nurrungar and controls the US Defence Support Program (DSP) early
warning satellites.
