The technology broke through

Satellites, through satellite television, GPS and weather forecasts, play a role in our daily lives. From first years in the 60th did a long way satellite technologies. There is no doubt that the satellite television is noticed as a first line of television these days but that is surprising that it actually was round more than 40 years. The first signal of satellite television was transferred from Europe to the Telestar satellite which was located at this time across North America in 1962. The next year saw start of the first geosynchronous communication satellite. Satellites with geosynchronous orbits are extremely important for technology of satellite television. They rotate round Earth on the speed compatible to Terrestrial rotation. Because of it they remain in the same relative part of the sky always, meaning that clients of satellite television should arrange only the satellite antennas once, and then should not worry further about finding of a signal. Intelsat I was the first commercial communication satellite started in 1965. In 1967 of Orbita it was created in the Soviet Union, officially becoming the worlds the first provider of satellite television.

The technology broke through to North America in 1972 and further extended around the world next years. While the basic principles of satellite television remained invariable, as those first years, processings in technology made it much more viable as alternative to cable. Probably, the most critical improvement in satellite television was the switch from analog signals to digital. The analog signal hands over information by means of changes in force of a signal.
