The billions of video, data and voice transmission are handled by fixed satellite.
Satellite Facts 7: A geostationary satellite
The orbit of a geostationary satellite begins from the west to the east. The satellite does not seem moving because it has the similar spinning direction with earth.
Satellite Facts 8: Polar-orbiting satellites
The satellite which orbits the earth from pole to pole providing the image of earth strip by strip is called polar-orbiting satellites.
