Satellite Uplink

In order for a satellite broadcast to take place, the point of origin must transmit (uplink) a signal to a satellite that it then relays back to Earth.

Geostationary orbit refers to a position in space, approximately 22,000 miles or 36,000 km over the equator, where the orbit speed of a satellite is equivalent to the speed of rotation of the earthGeostationary orbit refers to a position in space, approximately 22,000 miles or 36,000 km over the equator, where the orbit speed of a satellite is equivalent to the speed of rotation of the earth. When a satellite is in this position, the satellite appears to "stand still" or remain stationary in orbit.

Satellite broadcasting services generally use geostationary satellites. This allows an uplink to be pointed at a fixed position above the Earth.

One method to transmit the signal to a satellite is for an uplink truck equipped with audio and video control equipment, transmitters, and a satellite uplink dish, to transmit the source signal to a satellite.
