प्रश्न
Why are geostationary satellites not useful for studies of polar regions?
Advertisements
उत्तर
- The orbit of a geostationary satellite is above the equator.
- The time of revolution for the earth around itself and that for geostationary satellites to revolve around the earth being the same
- These satellites are stationary with reference to the Earth they can observer a specific portion of the Earth continuously.
- Therefore, geostationary satellites are not useful for studies of polar regions.
