1.   The satellites orbit at different heights.

2.   At that altitude, a satellite orbits Earth at the same speed that the planet rotates.

3.   Environmental satellites orbit hundreds or thousands of miles above Earth.

4.   Satellite television dishes face south, toward the equator, which the satellites orbit.

5.   Such satellites orbit so that they appear in a fixed spot in the sky.

6.   The satellite orbits at a point between Earth and the Sun where the gravity of each body cancels out the other and keeps the craft in a stable spot.

7.   These satellites must orbit directly over the Equator and must be separated by at least two degrees of longitude to keep them from interfering with each other.

8.   Watchful satellites orbit the pole daily.

9.   Thirty-four Raduga-type satellites are already orbiting the Earth, ITAR-Tass reported.
