A geostationary orbit, also referred to as a geosynchronous equatorial orbit[ a ] (GEO), is a circular geosynchronous orbit 35,786 km (22,236 mi) in altitude above Earth's equator, 42,164 km (26,199 mi) in radius from Earth's center, and following the direction of Earth's rotation.
Sep 18, 2024 · geostationary orbit, a circular orbit 35,785 km (22,236 miles) above Earth’s Equator in which a satellite’s orbital period is equal to Earth’s rotation period of 23 hours and 56 minutes. A spacecraft in this orbit appears to an observer on Earth to be stationary in the sky. This particular orbit is used for meteorological and ...

3. The geostationary orbit. Geostationary orbits of 36,000km from the Earth's equator are best known for the many satellites used for various forms of telecommunication, including television. Signals from these satellites can be sent all the way round the world. Telecommunication needs to "see" their satellite all time and hence it must remain ...
Apr 23, 2024 · Communication satellites in geostationary orbit are used to relay signals between ground stations and spacecraft in low Earth orbit, as well as to provide global coverage for satellite phone and internet services. Weather satellites in geostationary orbit are used to monitor and track weather patterns around the world, providing valuable data ...
Mar 28, 2022 · Geostationary satellite orbits can only be above the equator, so the polar regions are not covered. GSO is widely used in many satellite orbits models methods and applications, including live broadcast and communications or relay systems. Geo transfer orbit (GTO) Used to transition a satellite from LEO about 200 km high to GSO.

Mar 30, 2020 · An orbit is the curved path that an object in space (such as a star, planet, moon, asteroid or spacecraft) takes around another object due to gravity. Gravity causes objects in space that have mass to be attracted to other nearby objects. If this attraction brings them together with enough momentum, they can sometimes begin to orbit each other.

The geostationary orbit is a unique resource used by many satellites: its parameters must satisfy very precise conditions (circular orbit in the equatorial plane and at an altitude of 35,786 km) to have a fixed position in relation to the Earth. On the other hand, more and more operators want to place satellites on this orbit mainly for telecommunications applications.
