MCQ on Geostationary Satellite

MCQ on Geostationary Satellite: 

  • A geostationary satellite is a satellite orbiting the Earth in a geosynchronous orbit, which means it has the same period as the Earth. That is to say, the orbital speed of the geostationary satellite around the Earth is the same as the rotation speed of the Earth.
  • The orbits in which geostationary satellites operate are called geosynchronous orbits. When viewed from a specific location on Earth, a satellite in geosynchronous orbit appears in the same position in the sky after passing a sidereal day.
  • The circular geosynchronous orbit has a radius of 26,199 miles (42,164 kilometers).
  • Geostationary satellites are not necessarily geostationary satellites, but stationary satellites must be geostationary satellites.
  • Geostationary satellites are divided into geostationary orbit geostationary satellites, inclined orbit geostationary satellites, and polar orbit geostationary satellites.
  • Geostationary satellites play an important role in global communications and weather forecasting.
  • Geostationary satellites have many uses, such as communicating with space vehicles (such as the Hubble Telescope and spacecraft), audio communications, Internet, cable broadcast, wireless signals, and weather forecasting.
