what are geostationary satellites
Answers
Answer:
☘ It is an artificial satellite, which appears stationary to an observer on the Earth's surface .
☘ The orbit of Geostationary satellite should be circular and Caplanar with the equatorial plane of the earth .
☘ The angular velocity of geostationary satellite should have some magnitude and direction as that of Earth i.e., the angular velocity should be from west to east and period of revolution should be 24 hrs.
☘ The geostationary satellite is very useful for transmission of TV programmes,radio Signals and telephone talks .
☘ Geo stationary satellite is also called as Synchronous communication satellites .abbreviated as 'SYNCOMS'.
✿ The examples for geostationary satellites are;
☘ INSAT (Indian national satellite) series
☘ APPLE (Ariane passenger payload experiment) was the first Indian geostationary satellite
Answer:
geostationary satellite
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east)...
Explanation:
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east). At this altitude, one orbit takes 24 hours, the same length of time as the earth requires to rotate once on its axis. The term geostationary comes from the fact that such a satellite appears nearly stationary in the sky as seen by a ground-based observer. BGAN, the new global mobile communications network, uses geostationary satellites.
