From the Skies to Your Home: How Satellite TV Information is Sent
Different to terrestrial television, which is relayed by masts on the earth, satellite TV information is sent to and from satellites that are about 23,000 miles above the Earth’s surface.
In 1962, the first satellite TV information or signal was sent from Europe up to the Telstar satellite that was orbiting above North America. In 1973, Canada became the first to launch Anik 1, the first domestic satellite to carry satellite TV information in North America.
In the same way as all other satellite communications, satellite TV information begins in an uplink facility where a transmitting dish, aimed at the satellite that it is transmitting to, sends signals.
