Satellite Programming

Reference Guide for Satellite Programming

Satellite technology can be used to deliver live televised courses, programs, or meetings to multiple locations simultaneously across a wide geographic area. Generally one-way video and two-way audio, satellite programs involve at least one originating (uplink) site and a number of receive (downlink) sites. Downlink sites generally communicate with the uplink site by telephone or fax.

Basic Satellite Terminology


One of two common satellite frequency bands (Ku-band is the other). C-band earth stations use the 6 GHz frequency band to transmit and the 4 GHz frequency band to receive.


Transmission of radio frequency signals from a satellite to an earth station. A satellite dish that receives signals.


Pronounced "Kay-you band". One of two common satellite frequency bands (C-band is the other). Ku-band earth stations use the 14 GHz frequency band to transmit and the 12 GHz frequency band to receive.


Satellites are communication devices used in the broadcasting of radio, television, computer data, and the latest technology global positioning. Satellites are in orbit 22,300 miles (35,786 km) above mean sea level, positioned over the equator, and encircling the earth. This precise distance from earth places them in a Geostationary Orbit, meaning the satellites rotate at the same speed as the earth and thus appear to be stationary. Satellites receive and retransmit electromagnetic signals.


Satellite equipment that receives signals on the uplink, translates them to the downlink frequency, and amplifies them for retransmission to earth.


The signal path from an earth station to a satellite.
