geostationary orbits>

cn any1 explain it to me easily and intuitively

A geostationary orbit is one in which the speed at which a satellite orbits the Earth coincides with the speed that the Earth turns and at the same latitude, specifically zero, the latitude of the equator. This does not mean that the satellite and the Earth are traveling at the same speed, but rather that the satellite is traveling fast enough so that its orbit matches the Earth's rotation. A satellite orbiting in a geostationary orbit, therefore, appears to be hovering in the same spot in the sky, and is directly over the same patch of ground at all times.

A geosynchronous orbit is one in which the satellite is synchronized with the Earth's rotation, but the orbit is tilted with respect to the plane of the equator. A satellite in a geosynchronous orbit will wander up and down in latitude, although it will stay over the same line of longitude. Although the terms 'geostationary' and 'geosynchronous' are sometimes used interchangeably, they are not the same technically; geostationary orbit is a subset of all possible geosynchronous orbits.

if u dont get it even now!u can ask always ask me!!

I think he can read that in a book, too. Geostationary orbit is one in which the satellite has the same period(24 hours) as that of the rotation of Earth on its on axis. This makes the satellite seem stationary when viewed from Earth. As simple as that. You can add the details.

Anything appearing to be stationary when viewed from the surface of the earth is said to be in the geostationary orbit. For anything to be in the geostationary orbit it must satisfy following conditions:
1) it's time period must be that of the earth, i.e., 24 hr.
2) the angular velocity must be same as the earth's.
3) the direction of rotation should be same as the the earth's, ie, west to east.
4) it should lie in the equatorial orbit.

What do you mean?

^^ its very clear!!

I get it. Actually no. This is from a note my physics teacher taught me. The one i posted is the general definition. Can be found anywhere.
Will you please tell me the mark scheme which has the same content as this.

 

[hassam]

the orbit should lie directly above the equator.....this is the meaning of equatorial orbit???

Yes, along the earths equator.
