Sputnik 99 (Russian: Спутник 99, also Radio Sputnik 19 or RS-19) launched on April 2, 1999 from the Baikonur Cosmodrome on board a Soyuz-U-PVB launch vehicle. The nano-satellite was created in a joint-venture by Rosaviakosmos, Aéro-Club de France, and the Radio Amateur Satellite Corporation (AMSAT) as a marketing effort financially backed by The Swatch Group. Sputnik 99 was deployed from the Mir space station on April 16, 1999, even though its primary mission package, an amateur radio broadcast system (AR), had been purposely disabled, immediately rendering the satellite a piece of space flotsam.
