The Lampan Sampan satellites were part of a series of so called Program 11 or P-11 "Subsatellite Ferrets", low orbit ELINT/SIGINT satellites to pinpoint and characterize different Radar emitters in the Soviet Union and Warsaw pact states.
The Lampan Sampan SIGINT general search payloads were featuring two-meter diameter parabolic dish antennas.
These subsatellites were deployed from the propulsion rack of the Agena-D stage of KH-4A Corona reconnaissance satellites. They used a solid-fuel kick-motor to maneuver themselves into their operational orbits after deployment.
