satellite

Radio amateurs have been using satellites as long-distance radio transmitters for decades. There is always a lighthouse on board the satellite, which is used to transmit telemetry data and sometimes a transponder, Such a converter listens on one frequency and transmits on another. Popular satellites included the Soviet RS-12/13, Japanese FO-20 and FO-29, Indian VU-52 or AMSAT AO-7, AO-27. These satellites are often referred to as LEO orbits for low orbit. Working via satellites requires demands on technical and operator skills at VHF.

Currently, a geostationary satellite with a range from Indonesia to South America is also available to radio amateurs, QO-100.
