  2. Communications satellite - Wikipedia

    en.wikipedia.org/wiki/Communications_satellite

    A communications satellite is an artificial satellite that relays and amplifies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military ...

  6. Earth observation satellite - Wikipedia

    en.wikipedia.org/wiki/Earth_observation_satellite

    A geostationary orbit, at 36,000 km (22,000 mi), allows a satellite to hover over a constant spot on the earth since the orbital period at this altitude is 24 hours. This allows uninterrupted coverage of more than 1/3 of the Earth per satellite, so three satellites, spaced 120° apart, can cover the whole Earth.
