What is non-geostationary satellite?

Answer 1

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.

Answer 2

An orbit, in the plane of Earth's equator, in which the orbiting object will remain over the same position on Earth's surface as the Earth rotates. The orbiting object will appear to be stationary in the sky.

Answer 3

A non-geostationary satellite is one where its position relative to the Earth is not fixed.
