Geosynchronous
Describes the orbit path of a satellite. Geosynchronous means that the satellite is traveling 22,282 miles above the equator. Because of this positioning, a geosynchronous satellite travels at the same speed as the Earth, and thus appears stationary.

But due to the great distance information must travel between a geosynchronous satellite and earth, geosynchronous satellites are not ideal for digital interactive transmissions (such as a mobile phone call) because the signals take too long to travel between the satellite and the phone to produce a smooth-sounding phone call. Lower flying satellites are used in these instances. (Also see Motherboard)
