For a satellite to be in a particular orbit, a particular velocity is required or a given height above Earth ‘r0+h’.
Telecommunications satellites remain above one given point on the Earth’s surface, so are called geostationary.
Spy Satellites move in a polar orbit so that they can perform sweeps of the surface.
Formulae for calculating satellite orbits
ω = 2πf;
v = ωr;
a = ω2r
a=v2/r → v2=ar
