Basically there are two main types of orbits for satellites orbiting the Earth. They are LOW EARTH ORBITS and GEOSTATIONARY ORBITS.
Satellites in low Earth orbit are primarily about ~ 300km to ~ 800km above the Earth's surface. Since they have low altitude, their orbital velocity is quite fast and some can orbit the Earth in about one and a half hours. Satellites that use low Earth orbits include weather satellites and imaging satellites. Since they are close to Earth, the resolution of images is quite good.
Satellites in geo-stationary orbits go in a circular orbit around the Earth with a period of 24 hours (exactly 23 hours 56 minutes). It lies in the plane of the equator. Used for communication satellites, as they appear to remain stationary in space relative to the Earth.
