Why does a geosynchronous satellite not trace a path over the surface of Earth?
A geostationary orbit achieved by being in a location where the satellite's orbital period is 24 hours. This means the satellite is about 36,000 km (22,000 miles) above the Earth's surface. All orbits must therefore be over the equator. Every orbit around the earth looks like a circular (or elliptical) ring whose center (or one foci) is at the center of gravity of the Earth. An orbit exactly above the equator is one such orbit, but any orbit can be tilted as long as the center (or focus) stays at the Earth's center and the whole orbit is flat like a disk. On various NASA maps this makes the orbit look like a sinewave, but on a globe it stays a flat circle (or ellipse). On "Star Trek" I have seen errors a number of times on "Geostationary orbit over the North Pole", well you can't do that. Likewise, a "Lunar-stationary orbit" is impossible for a spacecraft, since Earth itself is already IN THE STATIONARY ORBIT POSITION! Remember that a geostationary orbit looks like it is always over the same spot on the Earth (or other body). If you were on the Moon, the Earth would be in the same position in the sky at all times.
What is the inclination of a satellite to the earths equator?
There is no set inclination of a satellites orbit to the earth's equator. Once in space, the spin of the earth or where it's poles happen to be become irrelevant to the satellite. Many satellites like spy and weather satellites orbit over the two poles (north and south) while communication satellites are placed in orbit directly above the equator at a height that is synchronised with the earth's orbit. This way they stay permanently above the same place on the equator and do not APPEAR to move at all.
How long does it take to build a satellite?
The time it takes to put together a satellite varies on the size and structure of the satellite. A simple satellite could be put together in a couple of months, where a large science mission could take ten or more years.
What is a geostationary satellite State two uses of a geostationary satellite?
In order for a satellite to stay in space and not fall to earth, it has to move in orbit round the earth. Many satellites and the International Space Station are in low orbit and at that distance above the earth orbit the earth in a couple of hours or so. However, if the orbit is around 26000 miles up, then at that distance the time it takes for a satellite to freely orbit is exactly one day or 24 hours. This means that the satellite is always above the same spot on earth, as the earth also takes 24 hours to rotate. Thus, if we could see the satellite in the sky it would not move across the sky like the International Space Station but it would stay in the same place in the sky. This means that they can be used for communication - when you telephone, say, from Europe to the USA then the signals are received by these satellites, amplified and relayed across the world to the receiver of the call. As the satellites are in the same place in the sky all the time, you can call at any time of the night or day. However, if the satellite moved across the sky in low orbit you would only be able to use it when it was in the sky - in other words you could only telephone for a few minutes at a time and then have to wait until it was back in the sky again. Similarly, these satellites are used for navigation in sat-navs. As the satellite is always in the same point in the sky, it can work out your position at any time of the night or day. The term 'geostationary' comes from 'geo' meaning 'earth' (as in geo-graphy, geo-thermal etc) and 'stationary' - meaning not moving i.e. the satellite is 'not moving above earth'.
What Keeps a Satellite In Space?
Once a satellite is launched into orbit, the force of gravity tends to pull it toward the Earth. But by moving fast enough, it falls in a curved path and circles the Earth. So orbit is something like a controlled fall. If a satellite does not move fast enough, it will eventually spiral closer to the Earth and burn up in the Earth's atmosphere. The same balance of gravity and speed keeps the moon and the International Space Station in orbit.

How can one make a spoon dropped from a satellite revolving around the earth land on earth?
If you have a lot of time, and a huge amount of expendable cash, you can place a reasonably massive satellite in orbit under the spoon. Over time the satellite's gravity will pull the spoon's orbit lower and lower. Eventually the spoon's orbit will decay and it will drop toward earth. Just wait. It will end up on Earth eventually. The satellite is already in orbit and will eventually fall into the atmosphere. Anything that falls off the satellite is going to eventually go 'down' to Earth.
How does a satellite stay in one place?
For a satellite to stay in one place over the earth, the satellite must be going in orbit in the same direction that the earth spins. The satellite must also travel at the same pace/speed as the earth spins to give us the 24-hour day that we as people witness. To apparently stay in one place it must be in a synchronous orbit. For the earth this is about 24,000 miles altitude. It must also be an equatorial satellite.
What is a geosynchronous orbit?
In a geosynchronous orbit, a satellite orbits Earth at the same rate as Earth rotates and thus stays over the same place on Earth all the time.
Why does it take 24 hours for a communications satellite to orbit Earth?
They take 24 hours to orbit earth so they will always be in the same place in the sky. This makes it easier for setting up satellite dishes for example, since they have to be pointed toward the satellite.
What was the first county to successfully launch a satellite and place it in an earth orbit?
think it was the soviet union.............
What is SATCOM?
Satellite communications. The use of satellites in orbit around the earth to relay data/voice from one place to the other. That's as basic of a definition as I can give you.
What type of orbit can orbit earth and have a orbital period equal to the rotation period of earth?
The term you are likely looking for is "Geosynchronous Orbit"Any orbit with a semi-major axis of about 22,000 miles has an orbital period of 24 hours.If the orbit is circular, then the satellite is always at the same longitude,but oscillates north and south every day.If the orbit is in the plane of earth's equator, then the satellite appears stationaryover one place on the earth's surface.A good example is any of the satellites that send TV to those little dishesmounted on everyone's garage.
Can you place an artificial setellite in any desired orbit or in perticular orbit around earth?
You can put it in any orbit you like, as long as the orbit follows a few simple rules: -- It must be elliptical. (A circle is an ellipse too.) -- One focus of the ellipse, or the center of a circular orbit, must be the center of the earth. -- No part of the orbit can dip into the atmosphere; if it does, then your artificial satellite and its orbit won't last long.
What is a geostation satellite?
Geostationary satellites orbit high above the surface of the earth at about 35,000km, directly above the equator. The take the same time to complete one orbit as the earths surface as it rotates meaning it is always above the same point on earth. They are used for TV and telephone signals as well as weather imagery, among other things. A satellites period, the time it takes it to go around the earth, is determined, in part, by its altitude. The further away it is then the longer it will take. You can calculate an altitude where it will take just one day to make an orbit. If this is done then though the satellite orbits the earth it appears to be stationary above one point of the earth. This orbit must be above, or very near to, the equator. For the earth this altitude is approximately 36,000 km (22,000 miles)
How long does it take earth satellite 42250km from earth take to orbit once?
this is if it is not a geostationary orbit, in which case it is always in the same place relative to earth. imagine a circle of radius 42250km+radius of earth(6,356km). it's perimeter is 2 x pi x 48606km = satellite's journey. then think of a really fast speed, which is the speed the satellite is moving at. divide the distance by speed and you have the time of one orbit However, by the height being 42250 , it makes me think the satellite is a geostationary satellite and so it would take 24 hours moving at approximately 12725 kmph does that answer your question?
What is the role of gravity in earth?
Gravity keeps things together here on Earth. It keeps the Earth together in the first place, and it keeps us on Earth. It keeps the Earth in orbit around the Sun, and it keeps the Moon in orbit around Earth.
What is the path of a planet or a satellite called?
A satellite is a body in orbit around another lager body. A probe is a machine sent to a specific place or specific course in space. Comment: That doesn't seem to answer the question. The curved path that a satellite follows is either a circle or an ellipse
