Radio ROSTO (also Radio-Sputnik-15 or RS-15 ) is the 15th Russian amateur radio satellite . The name ROSTO (РОСТО - Российская оборонная спортивно-техническая организация) stands for the Russian defense, sports and technical organization and was the interim name of the DOSAAF from 1991 to 2009.
RS-15 has a spherical shape (truncated cone-cylinder-truncated cone) about one meter in diameter and weighs about 72 kg. The satellite has no orientation or stabilization system and carries a linear transponder for Mode V / T . The transponder is divided into 10 segments with a bandwidth of 4 kHz each, which are controlled by separate AGC and have a transmission power of 0.4 watts. Linearly polarized dipole antennas serve as antennas. The radio payload comes from a Kaluga group of radio amateurs under the direction of Alexander Papkow.
mission
RS-15 was at 03.01 on 26 December 1994 UTC on the maiden flight of the Rockot carrier rocket from the Baikonur Cosmodrome launched. The command post is RS3A in Moscow. The transponder was then available to the amateur radio community. Shortly after the start, numerous connections in CW and SSB were made via the Mode A transponder.
The beacon 1 of the satellite is still active, while the transponder operation is no longer possible (as of January 2019).
