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.

For Earth orbiting satellites below the height of about 800 km, the atmospheric drag is the major orbit perturbing force out of all non-gravitational forces. [11] Above 800 km, solar radiation pressure causes the largest orbital perturbations. [12]
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. Although a collision is comparatively unlikely, GEO satellites have a ...

Each meteorological satellite is designed to use one of two different classes of orbit: geostationary and polar orbiting.
Polar orbits are used for Earth-mapping, reconnaissance satellites, as well as for some weather satellites. [2] The Iridium satellite constellation uses a polar orbit to provide telecommunications services. Near-polar orbiting satellites commonly choose a Sun-synchronous orbit, where each successive orbital pass occurs at the same local time of ...
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).
