low earth orbit satellite

Definitions

Electronics

  • An artificial satellite whose orbit ranges from approximately 500 to 2000 kilometers over the surface if the earth, although the defined value may vary. The time of orbit is much faster than that of a geostationary satellite, and a constellation of low earth orbit satellites are necessary to provide worldwide coverage, as they do not maintain a fixed spot above the planet at all times. Its lower orbit provides for shorter propagation delays, and reduced power requirements. This makes them suitable, for instance, for handheld devices used for paging, Internet access, and real-time conferencing. Its acronym is LEOS.
