 Description :  Chalet 1 was the first launch of a heavier, more advanced electronic intelligence satellite launched from Cape Canaveral aboard a Titan 3C rocket for the US Air Force. The project was renamed Vortex when the code name Chalet appeared in the New York Times.
The Chalet / Vortex ELINT satellites were the successors to the Canyon series of near GEO ELINT/SIGINT satellites. They were focussed on communications intelligence (COMINT), but had the capability added to intercept also missile telemetry.
