Why are communication satellites in geosynchronous orbits What is the prime advantage of lEOs?
Sambhav
Regarding the communications satellite orbit; a geosynchronous orbit is one that keeps the satellite in one position in the sky. It is a spot in space about 22,000 miles away that the satellite will orbit the earth once a day, so it is moving the same speed as the earth rotates and appears to never move. If your dish network satellite was not in geosynchrous orbit, you would need a device to turn your dish and there would be periods that the satellite would be over a different part of the world, like the sun and moon. They would slip over the horizon and you wouldn't be able to watch TV for a while.

Can people find satellites in geosynchronous orbits on earth s surface?
- No ...
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.
Why communication satellites have different aerials and positional orbits'?

What are the 2 orbits of satellites?
Artificial and natural satellites. Artificial satellites are man-made satellites sent into space for a variety of different purposes e.g. taking pictures of the earth for scientific investigation Natural satellites are moons, which orbit planets and are not man-made.
What is meant by a geostationary orbit?
A geosynchronous orbits refers to the orbit of a satellite that matches the rotation of the earth, allowing it to remain above the same line of longitude. The satellite may still move north and south but not east or west. A geostationary orbit is a specific type of geosynchronous orbit directly above the equator. This allows the satellite to remain completely stationary over a fixed point on the earth's surface.
Why communication satellites are stationed geostationary orbits?
the communication satellites take 24 hours to complete their one revolution around the earthso the orbit of revolving satellite is called geostationary orbit.
What is the preferred orbit for telecommunication satellites?
Geosynchronous orbits about 22,300 miles (35,900 km) above the earth and operate at frequencies near 4 gigahertz (GHz) for downlinking and 6 GHz for uplinking.
Does the space station orbit or is geostationary?
It orbits the Earth.However, even communications satellites in geosynchronous orbits are in orbit around the Earth; it's just that each orbit takes exactly one day, and so the satellite appears to be stationary above a point on the Earth. We can use this fact to our advantage; instead of building tracking antennas that follow a rapidly moving object, a tracking antenna for a geosynchronous satellite never needs to be turned.Which is a good thing, because those little "Dish" and DirecTV antennas can't be easily turned!
Why do satellites have different aerials and positional orbits?
Satellies have different aerials and positional orbits due to the molecular gravitional pull of the moon and the Earth's surface. The use of the aerials in the satellites assist in the communication between the microwave fields of the transmission towers.
Is Polar Orbit a type of Geosynchronous orbit?
No. A geosynchronous orbit is one in which the satellite stays approximately stationary with respect to a point on the earth's surface. This is not possible in any orbits which are not in the equatorial plane of the earth. For example, in polar orbits the satellites will move around the earth from above the north pole to above the south pole and then back to above the north pole. Clearly, this isn't stationary relative to the earth's surface.
How long does it take to do one rotation around the earth?
The answer depends on how close to the surface you are. The International Space Statioin orbits between 260 and 273 miles above the earth. It orbits the earth once ever 92 minutes and 50 seconds at a speed of 7,706.6 miles per second. Most manned missions orbit the earth in about 90 minutes. The one exception are the communication satellites which stay in Geosynchronous orbit at an altitude of 26,199 miles above the earth. A geosynchronous orbit means the satellite orbits with the rotation of the earth. In other words, it stays above the same point over earth at all times, meaning it never actually orbits the earth.
