You use satellites every time you watch television! These satellites orbit high above the Earth.

The satellites are always moving, so why don't you have to adjust your television every few minutes to keep up with the signals?

The reason the picture usually stays tuned in correctly is that the satellites that send the signals are in geosynchronous, or geostationary, orbit.
