Canyon

American military signals intelligence satellite. The first large US signals intelligence satellite. ELINT satellite built by Lockheed for NRO, USA. Launched 1968 - 1977.

Status: Operational 1968. First Launch: 1968-08-06. Last Launch: 1977-05-23. Number: 7 . Gross mass: 700 kg (1,540 lb).

Placed into near-geosynchronous orbits. They were misidentified by some analysts as missile warning satellites.

The first "stretched" Atlas SLV-3A/ Agena D was launched from the Eastern Test Range. The "stretched" Atlas had an additional 117-inch tank section to provide more fuel, a longer burn time, and increased payload capability. First launch in a communications intelligence program operated by the USAF within the National Reconnaissance Office, on behalf of the National Security Agency. The first generation series, CANYON, was based on the Agena vehicle. The Agena D remained attached to the spacecraft. Positioned in geosynchronous orbit over the Indian Ocean. Last known longitude (30 December 1968) 98.50 deg W drifting at 0.166 deg E per day.
