During the Cold War, the US intelligence agencies, such as the National Security Agency (NSA), were reportedly able to intercept Soviet microwave traffic using satellites such as Rhyolite/Aquacade. [1] Much of the beam of a microwave link passes the receiving antenna and radiates toward the horizon, into space.
Declassified photos taken by Cold War-era spy satellites have revealed hundreds of previously unknown Roman-era forts, in what is now Iraq and Syria, a new study found.
ECHELON, originally a secret government code name, is a surveillance program (signals intelligence/SIGINT collection and analysis network) operated by the five signatory states to the UKUSA Security Agreement: [1] Australia, Canada, New Zealand, the United Kingdom and the United States, also known as the Five Eyes.
In 2004, the base began operating a new satellite system known as the Space-Based Infrared System, which is a vital element of US missile defence. [10] Since the end of the Cold War, the station has mainly been employed to intercept and record weapons and communications signals from countries in Asia, such as China and North Korea.
