Geostationary orbit

• A geostationary orbit allows a satellite to hover over a constant spot on the Earth.
• The orbital period at this altitude is 24 hours.
• This allows uninterrupted coverage of more than 1/3 of the Earth per satellite.
• Three satellites, spaced 120° apart, can cover the whole Earth except the extreme polar regions.
• This type of orbit is mainly used for meteorological satellites.
