OSCAR is an acronym for Orbital Satellite Carrying Amateur Radio.
OSCAR series satellites use Amateur Radio to communicate with earth. They are conceived, designed, and built by Amateur Radio operators under the general direction of national organisations known as AMSAT.
OSCAR I - the first amateur satellite, launched December 12, 1961 by a Thor Agena B rocket from Vandenberg Air Force Base, piggybacked as ballast with Discover 36. It weighed 4.5 kg and was placed in a 372 x 211 km orbit, inclined 81.2 degrees, with an orbital period of 91.8 minutes. Over 570 amateurs in 28 countries heard its Morse code "hi hi" message on the two meter band. Its 140 mw battery-powered transmitter lasted 3 weeks.
