In 1929, Herman Potočnik described both geosynchronous orbits in general and the special case of the geostationary … See more

Most commercial communications satellites, broadcast satellites and SBAS satellites operate in geostationary orbits.
Geostationary communication satellites are useful because they are visible from a large area of the … See more

Geostationary satellites are launched to the east into a prograde orbit that matches the rotation rate of the equator. The smallest inclination that a satellite can be launched into is that of the launch site's latitude, so launching t… See more

Geostationary satellites require some station keeping to keep their position, and once they run out of thruster fuel they are generally retired. The transponders and other onboard systems often outlive the thruster fue… See more

A typical geostationary orbit has the following properties:
• Inclination: 0°
• Period: 1436 minutes (one sidereal day)
• Eccentricity: 0… See more

A geostationary orbit can be achieved only at an altitude very close to 35,786 kilometres (22,236 miles) and directly above the equator. This equates to an orbital speed of 3.07 kilometres per second (1.91 miles … See more

For circular orbits around a body, the centripetal force required to maintain the orbit (Fc) is equal to the gravitational force acting on the satellite (Fg):
From Isaac Newton's universal law of gravitation… See more
