Why communication satellites are stationed geostationary orbits?

the communication satellites take 24 hours to complete their one revolution around the earth
so the orbit of revolving satellite is called geostationary orbit.

Why does a satellite travel over different parts of the earth?
Because most satellites are not 'geostationary'. A geostationary satellite orbits the Earth at the same speed that the Earth spins on its axis - such as the GPS grid, or TV relay satellites. Most satellites travel faster or slower than the Earth spins.
Is the Hubble telescope a geostationary satellite?
No, the HST orbits at 570 km above Earth (and not 36,000 km as the geostationary satellites do). It flies round Earth (= one orbit) in 97 minutes, the speed is about 28,000 kilometers per hour.
What are the suns satellites?
A satellite is an object that orbits a planet. The Sun is a star so it does not have satellites. Actually a satellite is anything that orbits another. So the planets and asteriods are the sun's satellites.
What are the types of satellites orbits?
There are basically three types of orbits.* Sun Synchronous Orbits * Polar Orbits * Geosynchronous Orbits There are variations on these types. Visit related link below.
Is aphopis coming to earth?
Apophis will pass near the Earth on April 13, 2029 within the orbits of geosynchronous communication satellites. It will not come closer to Earth than 19,400 miles.
What are the two main types of satellite orbits?
geostationary andGeosynchronous satellites
What has the author E M Soop written?
E. M. Soop has written: 'Handbook of geostationary orbits' -- subject(s): Artificial satellites, Control systems, Data processing, Geostationary satellites, Orbits, PEPSOC
What is a geostationary satellite?
Geostationary is the moving orbit in the plane of the equator. Geostationary satellites are 22,300 miles above the Earths surface, and remain stationary at a fixed point. Weather and communication satellites are examples of geostationary satellites.
What devices need satellites in geostationary orbits?
Satellite terminals with fixed antennas, such as the TV dish on the garage or the corner of the house.
What is isochronous satellites?
An isochronous satellite is one that orbits the earth in one day. So it orbits the earth as the same speed as the earth rotates. Most satellites that are isochronous are infact geostationary satellites as they also stay in the same position above the earth. However these satellites occupy a very specific orbit above the equator. It is possible to have isochronous satellites that aren't geostationary however getting them to remain in orbit would prove difficult.

Why communication satellites have different aerials and positional orbits'?

What satellite orbits around the earth and takes the same time it takes for the earth to rotate on its axis?
Only artificial, geostationary satellites.
How far above the earth is geostationary orbit?
Geostationary satellites are in an orbit that's 22,282 mi (35,786 km) above the surface of the Earth. For more on Geostationary satellite orbits, visit http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx
What are the strategic locations of satellites?
There are two special locations for satellites: * geostationary orbits * polar orbits For satellite communication, it is very convenient if one can align fixed ground antenna to point at the satellite. The only way to get a satellite to stay exactly in front of a fixed ground antenna is to put it in geostationary orbit -- an altitude of 35,786 km above sea level above the equator. Other than geostationary orbit, there are a few other orbits that hold a satellite approximately in front of a fixed ground antenna for several hours -- the Molniya orbit and the Tundra orbit. Satellites designed to take photos of Earth (weather satellites, spy satellites, etc.) are typically in a polar orbit. Sooner or later, a satellite in polar orbit will end up directly overhead any given point on Earth. Typically these satellites are in an orbit very roughly 1000 km above sea level (roughly 100 minute orbit), because higher orbits are more expensive, and orbits less than a few hundred km rapidly decay from air friction.
Is the Hubble telescope a geostationary satellite?
No, the HST orbits at 570 km above Earth (and not 36,000 km as the geostationary satellites do). It flies round Earth (= one orbit) in 97 minutes, the speed is about 28,000 kilometers per hour.
How many days does it tack to orbit the Earth?
The ISS orbits the Earth in about 90 minutes. Some satellites are in geostationary orbit, orbiting in exactly one day. The Moon orbits (moves around) the Earth in about 28 days!
