Pine Gap

Pine Gap is a joint Australian–United States satellite communications and signals intelligence surveillance base and Australian Earth station approximately 18 km (11 mi) south-west of the town of Alice Springs. It is jointly operated by Australia and the United States, and since 1988 it has been officially called the Joint Defence Facility Pine Gap (JDFPG); previously, it was known as Joint Defence Space Research Facility. It plays a crucial role in supporting the intelligence activities and military operations of the US around the world. The station is jointly run by the Australian Defence Force (Australian Signals Directorate), the US Central Intelligence Agency (CIA), US National Security Agency (NSA), and US National Reconnaissance Office (NRO) and is a key contributor to the NSA's global interception/surveillance effort, which includes the ECHELON program. The classified NRO name for the Pine Gap base is Australian Mission Ground Station (AMGS), while the unclassified cover term for the NSA function of the facility is RAINFALL.
