Artificial satellites are classified based on their revolving orbits as:
Equatorial satellites
Polar satellites
Equatorial satellites and polar satellites are the two different types of satellites classified based on the revolving orbit around the earth. Equatorial satellites revolve around the earth through an orbit above the Equator whereas polar satellites revolve above the North-South poles of the earth.
Geostationary satellites are a type of equatorial satellite those which have their period of rotation equal to the period of rotation of the earth.
