Its called a geostationary satellite. Its quite far out, meaning its 24 hour orbit is quite long when compared with satellites closer in to earth. Is appears stationary in our skies, in the same spot throughout its orbit. This makes it a lot easier to track, a fixed dish can be used.
That is called a geosynchronous orbit.
Sputnigg Jr
Earth's rotation should eventually be synchronized with the Moon's orbit.
Geosynchronous orbit.
A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.
The area of the earth which is imaged during a satellite orbit is referred to as the satellite swath and can range in width from ten to hundreds ofkilometers. As the satellite orbits the earth a different area is covered due to the earth's rotation. The elevation of the satellite orbit is designed so that the same location will be retraced (imaged) in a period of several weeks.
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
That would be "revolution", not "rotation". Let's assume you need a certain speed for a circular orbit. If the satellite (in this case) has a bit less speed, it will get closer and closer to the Earth, during half of its orbit. While doing this, its speed will increase; during the other half of its orbit, this speed will make it go away from the Earth again. The final result is that it moves around the Earth in an ellipse. This assumes, of course, that it doesn't approach the Earth too much. If it gets too close, it will be slowed down by the atmosphere, and eventually crash to Earth.
Both of those words refer to points in the orbit of an earth satellite ... the moon or any artificial satellite. Apogee . . . the point in the orbit where the satellite is farthest from the earth. Perigee . . . the point in the orbit where the satellite is closest to the earth.
You would see the satellite in the same direction all the time. The satellite is supposed to move around the Earth at the same speed as Earth's rotation.
1. Rotation (earth rotates on it's axis) 2. Orbit (earth orbit's arount the sun)
As a noun: The rocket placed the satellite into a high Earth orbit. As a verb: The satellite had to travel very fast to orbit the Earth.
