What is the difference between a geosynchronous orbit and a geo stationery orbit
A geosynchronous orbit is any orbit which has a period equal to the earth's rotational period.
As we shall soon see, this requirement is not sufficient to ensure a fixed position relative to the earth.
While all geostationary orbits must be geosynchronous, not all geosynchronous orbits are geostationary. Unfortunately, these terms are often used interchangeably.
A geostationary orbit (or Geostationary Earth Orbit - GEO) is a geosynchronous orbit directly above the Earth's equator (0 latitude), with a period equal to the Earth's rotational period and an orbital eccentricity of approximately zero. From locations on the surface of the Earth, geostationary objects appear motionle ...more
Geo comes from ancient Greek and means earth.
"Stationary", has its origin in the 1400s and means, as most people know, fixed in one place, not moving.
"Synchronous", has its origins in the 1600s with Latin and Greek roots and means: occurring at the same time.
So, a geostationary satellite is a satellite that has an orbit that appears fixed in one place relative to a point on the Earth. This type of orbit will only work for satellites that are in a circular orbit, which is in the same plane as that defined by the Earths equator. For this to occur, the satellite has to be at an orbital altitude of 22,236 miles (35,786 km). Many weather and communication satellites, including satellite TV and radio are in geostationary orbits, which gives them the ability to cover large areas of the Earth. This also explains why your satellite dish can remain poin ...more
