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).
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.

Each meteorological satellite is designed to use one of two different classes of orbit: geostationary and polar orbiting.
To avoid confusion, geosynchronous satellites that are not in geostationary orbit are sometimes referred to as being in an inclined geostationary orbit (IGSO). Some of these satellites are separated from each other by as little as 0.1° longitude. This corresponds to an inter-satellite spacing of approximately 73 km.
GSAT-8 was launched on May 21, 2011, from Kourou, French Guiana. The rocket, an Ariane 5 was the carrier, marketed by the European Arianespace . First satellite to carry GAGAN payload followed up by GSAT-10 and in-orbit spare GSAT-15 .

GOES-8, known as GOES-I before becoming operational, was an American weather satellite, which formed part of the US National Oceanic and Atmospheric Administration's Geostationary Operational Environmental Satellite system. It was launched in 1994, and operated until 2004 when it was retired and boosted to a graveyard orbit.
Satellites under the Tongxin Jishu Shiyan cover appear to compose three separate classes, all in geostationary orbit and performing a military or intelligence mission. These include the purported Qianshao-3 SIGINT class, the Huoyan-1 early warning class, and an unknown class for TJS-3 and its subsatellite.
