A geostationary orbit is an orbit of the Earth that is circular, over the equator,
and at the right distance to have a period of 24 hours. A satellite in such an orbit
appears to hang motionless, always at the same point in the sky
Anything else is a non-geostationary orbit. A satellite in one of those appears to move
in the sky, so that if you want to communicate with it, you need a movable dish.
Non Geo stationary satellite is that satellite which has different angular velocity from earth and not placed on the height of 36000 Km from the earth. If you use Geo stationary satellite than only 3 satellites are enough to cover whole world. most of satellite are geostationary and they are(most of them) active satellites too.

A geostationary orbit around the Earth has a radius of approximately 42,164 kilometers.
A geostationary satellite does not trace a path over the surface of the earth because that is what geostationary means - the satellite is stationary over a point on the Earth.
The height of a geostationary satellite from the surface is approximately 35,786 kilometers (22,236 miles).
Geostationary satellites are in an orbit that's 22,282 mi (35,786 km) above the surface of the Earth. For more on Geostationary satellite orbits, visit http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx
it carries wind into the earth.
Geostationary satellite
No. Geostationary orbits are equatorial, but equatorial orbits are not necessarily geostationary. To be geostationary, the orbit needs to be equatorial, circular and at the altitude such that one orbit takes one sidereal day (approximately 24 hours 3 minutes 56 seconds. ) An equatorial orbit need only be located above the equator, may have any period and need not be circular.
It should be possible to have the perfectly geostationary satellites. But it is not possible. Perfectly geostationary satellite can not be made. Such satellite is pulled away by other objects like moon, sun and other planets from different directions. This force changes the velocity of the satellites.
