Radio 1 , Radio Sputnik 1 , RS-1 is a former Soviet amateur radio satellite .
construction
The amateur radio satellite Radio 1 was developed and built parallel to Radio 2 by students from the Moscow Energy Institute . Both satellites are similar, but not identical in construction. The power supply came from solar cells and chemical voltage sources. The satellite carried a command receiver for remote control and a beacon transmitter that also sent telemetry data. He also carried a 40 kHz wide linear transponder that converted signals from the 2 m band to the 10 m band. A 0.5 µV signal at the input of the receiver generated an output power of 100 mW at the output of the converter. The maximum output power of the linear transponder was 1.5 W. Radio 1 had a dipole antenna (inverted vee) for the 2 m band and a quarter-wave antenna (rod antenna) for the 10 m band.
mission
The satellite was launched on October 26, 1978 together with RS-2 and the dummy satellite Kosmos 1045 with a Russian Zyklon-3 launcher from the Plesetsk Cosmodrome in Russia. The command stations were located in Moscow (call sign RS3A), in Arsenyev (RS0A) and near Novosibirsk (RS3B). Radio 1 ceased operations in March 1979.
