It would need to be launched into a tangent plane parellel to that of the earth's orbit around the sun, with the same speed of rotation around the sun

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.
