  2. Geostationary orbit - Wikipedia

    en.wikipedia.org/wiki/Geostationary_orbit

    Space debris at geostationary orbits typically has a lower collision speed than at low Earth orbit (LEO) since all GEO satellites orbit in the same plane, altitude and speed; however, the presence of satellites in eccentric orbits allows for collisions at up to 4 km/s (14,400 km/h; 8,900 mph). Although a collision is comparatively unlikely, GEO ...

  3. Geosynchronous orbit - Wikipedia

    en.wikipedia.org/wiki/Geosynchronous_orbit

    The geostationary satellite (green) always remains above the same marked spot on the equator (brown). A geostationary equatorial orbit (GEO) is a circular geosynchronous orbit in the plane of the Earth's equator with a radius of approximately 42,164 km (26,199 mi) (measured from the center of the Earth).

  4. Communications satellite - Wikipedia

    en.wikipedia.org/wiki/Communications_satellite

    The article described the fundamentals behind the deployment of artificial satellites in geostationary orbits to relay radio signals. Because of this, Arthur C. Clarke is often quoted as being the inventor of the concept of the communications satellite, and the term 'Clarke Belt' is employed as a description of the orbit.

    A number of weather satellites are also present in geosynchronous orbits. Not included in the list below are several more classified military geosynchronous satellites, such as PAN . A special case of geosynchronous orbit is the geostationary orbit , which is a circular geosynchronous orbit at zero inclination (that is, directly above the ...

  6. List of BeiDou satellites - Wikipedia

    en.wikipedia.org/wiki/List_of_BeiDou_satellites

    This is a list of past and present satellites of the BeiDou/Compass navigation satellite system.As of December 2023, 44 satellites are operational: 7 in geostationary orbits (GEO), 10 in 55° inclined geosynchronous orbits (IGSO) and 27 in Medium Earth orbits (MEO).

  7. Satellite navigation - Wikipedia

    en.wikipedia.org/wiki/Satellite_navigation

    BeiDou started as the now-decommissioned Beidou-1, an Asia-Pacific local network on the geostationary orbits. The second generation of the system BeiDou-2 became operational in China in December 2011. [13] The BeiDou-3 system is proposed to consist of 30 MEO satellites and five geostationary satellites (IGSO). A 16-satellite regional version ...

    Amazon’s Project Kuiper aims to put more than 3,000 satellites in orbit to compete with SpaceX’s Starlink service.

  9. Geosynchronous satellite - Wikipedia

    en.wikipedia.org/wiki/Geosynchronous_satellite

    Satellites in geostationary orbit. A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.Such a satellite returns to the same position in the sky after each sidereal day, and over the course of a day traces out a path in the sky that is typically some form of analemma.
