# Glossary Definition for: Satellite

Satellites in orbit above the earth are invaluable for long- distance communications.
Some satellites are geosynchronous, which means they sit directly over a fixed point on the equator and are always in the exact same position in the sky. But because they are so far away, precise aiming with a dish-style antenna is essential.

Others satellites are deployed in “constellations” with multiple satellites in a lower orbit working together, with the goal being that at least one satellite in the constellation is always in view.

Because low earth orbit satellites are much closer and are in constant motion, aiming at them is not practical nor needed.
