RADIO ROSTO is the fifteenth Russian amateur radio spacecraft. ROSTO is an acronym for Russian Defence, Sports, and Technical Organization. The initial orbit was 2165 x 1885 km, with an inclination of 64.6 deg. The 70-kg micro-satellite carries linear communications transponders. It is spherical in shape and about 1 m in diameter. The onboard electronics equipment was designed and built by a group of radio amateurs from Kaluga, a town 180 km SW of Moscow. Radio-ROSTO was seen as the precursor to a proposed constellation of Radio-M spacecraft. Also launched by Rokot but into orbits of 950 - 1,000 km at 65 degrees, the network would consist of up to 6 spacecraft working with uplink and downlink frequencies of 435 MHz and 146 MHz and an output transmitter power of 20 W. Radio M spacecraft will be nearly twice as massive with a total mass of 120 kg. An alternative system would consist of six Radio-ROSTO class spacecraft in circular orbits near 1,950 km at inclinations of 65 degrees.
