They orbit at a hieight of 22,000 miles so that they always stay at the same point above the earth.

Yes, geostationary satellites orbiting the earth at 22000 miles altitude will stay directly over the same point of the earth only if the satellite is in an equatorial orbit(orbiting around the equator). And of course, that point will be somewhere on the earth's equator. However, if the "geostationary" satellite is not in an equatorial orbit, then the satellite will only be directly over a given line of longitude. But the latitude will vary from the satellite's furthest latitude north, say (N) degrees, to the satellite's furthest latitude south, which would be (-N) degrees. Technically, this "geostationary" satellite, isn't a geostationary satellite.

Geostationary satellites are satellites in orbits that keep them in the same place relative to Earth's surface, though they are moving. Practically, this keeps your satellite dish from needing motors to swivel it around.

At 140 miles up you orbit the earth in about an hour and a half. The higher you go, the longer it takes, because you have further to orbit, and you're going slower. At about 22,000 miles it takes 24 hours to orbit the earth. So, if you're circling the equator and going the same direction the earth is spinning, you'll stay over the same point on the globe.

they are satellites that maintain their position relative to a point on the earths surface. they can be at any altitude, however most are no more than 33,000 miles up. their orbital velocity is made to match the rotation of the earth, therefore, although they are moving many thousands of miles an hour, they appear to be stationary.

They are satellites that orbit at the same speed our planet does so it stays in the say place all the time.

They are satellites that stay in the same spot above the earth as it rotates

It is a electonic device orbiting around the Earth with the same speed that our planet.
