The satellites were primary built to intercept soviet communications transmissions, especially line-of-sight microwave links, but were also able to tap into very high frequency (VHF) communications. Main contractor was Lockheed. Reportedly they consisted of a large (ca. 10 m diameter) antenna and were three axis stabilized. They were deployed into a 24 h orbit, which is not geostationary, so that triangulations of emmiter sources can be made from different points. Parola chiave :
