LEO satellites – Low Earth orbit satellites in HamRadio.

LEO satellites have a circular (or elliptical) orbit at the height of 250–2000 km from the Earth’s surface. The maximum time during which a satellite is above the local horizon for an observer on the Earth is up to 20 min.

This time is used to transfer data, images, and photographs to selected ground stations positioned in strategic locations.

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 amateur radio repeaters that can be communicated by using commonly available amateur radio equipment.

Antennas Amplifiers (AA) equipment is available in backorder only, and will be shipped within 10 to 15 days after the order.
