a geostationary satellite for communications seems to be in a fixed spot above the equator because it has the same angular velocity as the earth.

Remember that all satellites and debris in GEO and below must cross the equator twice per orbit.
A geostationary satellite is in a geostationary orbit, which can only be achieved at an altitude very close to 35,786 km (22,236 m) and keeps the satellite fixed over one longitude at the equator.

In fact, there cannot be a geostationary satellite anywhere else, except above the equator(in an equatorial orbit).

That means that it's not geostationary; it's drifting from north to south and back again. Similar Questions. A geosynchronous orbit is a high Earth orbit that allows satellites to match Earth's rotation. As it so happens, that’s simply not true. They can still be geosynchronous, however, so they still go round the earth in 24 hours. satellite's orbital period is 24 hours.

Such a satellite returns to the same position in the sky after each sidereal day , and over the course of a day traces out a path in the sky that is typically some form of analemma . 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.
Geostationary satellites. So... See full answer below. The closest it can be to geostationary is geosynchronous -- passing above the same … Similar Questions.

Any other orbital plane means they bob up and down through the equator, therefore are not geostationary. It is not possible to have a satellite that is stationary over …

That means that it's not geostationary; it's … There cannot be a geostationary satellite at the poles, basically because it would have to be at rest, which cannot happen as it would get pulled by the earth's gravity and eventually crash to the surface. asked by Shaila on August 23, 2010; physics. If the orbit of a satellite is inclined or polar then the satellite will not remain at the same point relative to a particular point on the earth. I was trying to figure this out too. This is fairly easy to prove. This is fairly easy to prove. Above the equator is the only place they can be geostationary, as they are orbiting around the Earth at the same rate as the ground beneath them.

Located at 22,236 miles (35,786 kilometers) above Earth's equator, this position is … It's impossible to have a geostationary orbit above any other plane than the equator because the satellite would experience a force towards the Earth's centre taking it away from it's geosynchronous orbit. A satellite orbits around the centre of the Earth, so its track always follows a great circle.

Imagine that you wanted a satellite directly above the place where you are right now, lets say 500 km away. 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). If the satellite passes directly above any point that's not on the equator then it must either be to the north or south of it, and the corresponding great circle will be half to the north, half to the south of the equator. Geostationary. about 36,000 km (22,000 miles) above the Earth's surface. In fact, there cannot be a geostationary satellite anywhere else, except above the equator(in an equatorial orbit).

However, many people get confused between geosynchronous and geostationary satellites, and tend to assume that both are basically the same thing. There are several hundred communication satellites and several meteorological satellites in such an orbit. Geostationary is a very specific type of geosynchronous orbit, where the satellite is permanently overhead at the same location (it's orbital period is equal to the Earth's rotational period).

It is not possible, for example to orbit in only the northern hemisphere or over the north pole. Geostationary satellite orbits can only be above the equator and therefore polar regions cannot be covered.

Geostationary satellites do this by orbiting the earth at approximately 22,300 miles above the equator. Physics - Geostationary Satellite.

Any other orbital plane means they bob up and down through the equator, therefore are not geostationary. Homework Statement Explain why a geostationary satellite must be placed vertically above the equator. If the satellite passes directly above any point that's not on the equator then it must either be to the north or south of it, and the corresponding great circle will be half to the north, half to the south of the equator. This one special quality makes it unique from geosynchronous orbits. But I got it as soon as I came across your explanation.
