A satellite truck is a mobile communications satellite earth station, typically mounted on a truck chassis as a platform. They are used for remote television broadcasts, to transmit the video signal back to the studio or production facility for editing and broadcast. Satellite trucks usually travel with a production truck, which contains the video cameras, sound equipment and crew. A satellite truck has a large satellite dish antenna which is pointed at a communications satellite, which relays the signal back down to the studio. Satellite communication allows transmission from any location that the production truck can reach, provided a line of sight (direct view) to the desired satellite is available.
