LEO satellites – Low Earth orbit satellites for Ham Radio
LEO satellites have a elliptical orbit at a height of 250–2000 km from the Earth surface. The maximum time during which a satellite is above the local horizon for an observer on the Earth is up to 20 min. A number of low earth orbit (LEO) OSCAR satellites use frequency modulation (FM). These are also commonly referred to as “FM LEOs” or the “FM Birds”. Such satellites act as FM repeaters that can be useed with available amateur radio equipment.
