GEOSTATIONARY SATELLITES

Geostationary Satellites


  • Geostationary satellites are higher than polar satellites. They follow the orbit
  •  of the Earth, they orbit above the equator.
  • They take 24 hours to orbit the Earth completely.
  • They are used for communication, so things like, TV and telephones.

POLAR SATELLITES

Polar Satellites

  • Polar satellites are low satellites that orbit over the North and South Poles.
  • They are used for spying and weather. Because the satellites are lower, they can see things on Earth in more detail.
  • They take about 50 minutes to orbit the Earth entirely. This is useful as the weather can be predicted more than once a day.

Frenchie

In the AQA book it says Polar Satellites take 2/3 hours to complete one full orbit around the orbit

Diamanti

THEY DON'T TAKE AS LONG AS GEOSTATIONARY ORBITS, THATS ALL THAT MATTERS.

THEY ROTATE THE EARTH MANY TIMES IN A DAY
