The POPPY program was a continuation within NRO's Program C of the Naval Research Laboratory's Galactic Radiation and Background (GRAB) ELINT program, also known as Tattletale. The National Security Agency was given the responsibility of collecting, interpreting, and reporting the signals intercepted. There were seven launches of POPPY satellites from Vandenberg Air Force Base from 1962 until 1971, all of which were successful. The program continued until August 1977.
