Overview
Pine Gap is a satellite surveillance base and Australian Earth station approximately south-west of the town of Alice Springs, Northern Territory in the center of Australia. 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.
The station is partly run by 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 included 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.
The base
The facilities at the base consist of a massive computer complex with 38 radomes protecting radio dishes and operates with over 800 employees. NSA employee David Rosenberg indicated that the chief of the facility was a senior CIA officer at the time of his service there.
