Satellites in geosynchronous orbit

Syncom (for "synchronous communication satellite") started as a 1961 NASA program for active geosynchronous communication satellites, all of which were developed and manufactured by the Space and Communications division of Hughes Aircraft Company (now the Boeing Satellite Development Center). Syncom 2, launched in 1963, was the world's first geosynchronous communications satellite. Syncom 3, launched in 1964, was the world's first geostationary satellite.

Eutelsat Quantum is a communications satellite developed in the framework of a public-private partnership between the European Space Agency, Eutelsat and Airbus Defence and Space. Operated by Eutelsat, its design allows for it to reconfigure its radios coverage zone and alter its performance according its needs. It is located in a geostationary orbit and its longitude may be modified to cover any region in the world.

Telkom-1 was a geosynchronous communications satellite built by Lockheed Martin, (Sunnyvale, California), for Indonesia's state-owned telecommunications company, PT Telekomunikasi Indonesia Tbk (PT Telkom). It operated for almost 18 years, more than two years past designed lifetime of 15 years.

The Geostationary Operational Environmental Satellite (GOES), operated by the United States' National Oceanic and Atmospheric Administration (NOAA)'s National Environmental Satellite, Data, and Information Service division, supports weather forecasting, severe storm tracking, and meteorology research. Spacecraft and ground-based elements of the system work together to provide a continuous stream of environmental data. The National Weather Service (NWS) and the Meteorological Service of Canada use the GOES system for their North American weather monitoring and forecasting operations, and scientific researchers use the data to better understand land, atmosphere, ocean, and climate dynamics.

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. A special case of geosynchronous satellite is the geostationary satellite, which has a geostationary orbit – a circular geosynchronous orbit directly above the Earth's equator. Another type of geosynchronous orbit used by satellites is the Tundra elliptical orbit.

GOES-17 (designated pre-launch as GOES-S) is an environmental satellite operated by the National Oceanic and Atmospheric Administration (NOAA). The satellite is second in the four-satellite GOES-R series (GOES-16, -17, -T, and -U). GOES-17 supports the Geostationary Operational Environmental Satellite (GOES) system, providing multi-spectral imaging for weather forecasts and meteorological and environmental research. The satellite was built by Lockheed Martin, based on the A2100A platform, and expected to have a useful life of 15 years (10 years operational after five years of standby as an on-orbit replacement). GOES-17 is intended to deliver high-resolution visible and infrared imagery and lightning observations of more than half the globe.

A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites are mainly of two types: polar orbiting (covering the entire Earth asynchronously) or geostationary (hovering over the same spot on the equator).

A geosynchronous orbit (sometimes abbreviated GSO) is an Earth-centered orbit with an orbital period that matches Earth's rotation on its axis, 23 hours, 56 minutes, and 4 seconds (one sidereal day). The synchronization of rotation and orbital period means that, for an observer on Earth's surface, an object in geosynchronous orbit returns to exactly the same position in the sky after a period of one sidereal day. Over the course of a day, the object's position in the sky may remain still or trace out a path, typically in a figure-8 form, whose precise characteristics depend on the orbit's inclination and eccentricity. A circular geosynchronous orbit has a constant altitude of 35,786 km (22,236 mi).
