The History Of Satellite TV - Family

Satellite TV provides the cutting edge of television options today. Because of the technology's position towards the front of the pack, many are surprised to learn that satellite TV has been around for more than four decades.

The first satellite TV signal was transmitted from Europe to the Telestar satellite, which at the time was positioned over North America, in 1962. The following year saw the launch of the first geosynchronous communications satellite.

Satellites with geosynchronous orbits are crucial to the satellite TV technology. They orbit the Earth at a speed consistent with the Earth's rotation. Because of this, they stay in the same relative part of sky at all times, meaning that satellite TV customers must only position their satellite dishes once, and then need not worry further about finding a signal.

Intelsat I was the first commercial communications satellite, launched in 1965.

The First Provider

In 1967, Orbita was created in the Soviet Union, officially becoming the world's first satellite television provider. The technology made it's way to North America in 1972 and further spread throughout the world in the following years.

While the basic principles of satellite television have remained unchanged since those early days, refinements in the technology have made it far more viable as an alternative to cable.

The switch to digital from analog signals was probably the biggest advance in satellite TV. An analog signal transmits information through variations in the strength of a signal.

A good way to think of an analog signal is to imagine a long rope with one end tied to a tree and the other end in your hand. If you snap the rope, you'll see the curved section moving from your hand to the tree.

An analog signal is much like that curved, moving section. Digital signals are comprised of ones and zeros. It is much harder to corrupt an digital signal compared to an analog signal.

When used for a technology that transmits signals across over 20,000 miles from the satellite to the receiver dish on your roof, having a stable signal is crucial.

The Advent of HD

Over the past few years, high definition television has proven itself to be the future of viewing. Cable companies have started to transmit some of their signals in high definition, however their overall capacity for high definition is determined by how much information can physically be transmitted along the actual cables.

Because it transmits signals through the air, Satellite TV isn't hindered by these restrictions.

History of Satellite TV - Technology - Communication

Human imagination has the power to visualize the future, seek visionary solutions to problems, guide people to inventions that change the face of the earth, and the fate of humankind. Inventions and discoveries for centuries, motivated by inspiring ideas of a few, including the heretic science fiction stories of Jules Verne, H.G. Wells and others, have helped us to reach this stage of modern technology. Such has been the revelation of Arthur C. Clarke in his classic 'Extraterrestrial Relays', published in 1945, in which he wrote about having satellites in special orbits 22,300 miles above the equator, based on calculations done in 1928 by the astronautics pioneer Herman Potocnik Noordung, to facilitate global communication. The idea sparked and broke like fire, with the Russians coming up with the world's first satellite, Sputnik in 1957, closely followed by the Americans in early 1958.

9 Foot Dish to 2 Foot Dish to No Dish - Satellite TV - Entertainment - Television

The 9 foot Dish: I remember when to have satellite TV, you needed a giant dish that made it look like you were a part of the space program and a special receiver. Starting prices were around $1500 to $2000 to get the equipment and have it installed. Then, you could get a lot of channels for free, but most of the "good channels" required some sort of subscription. The trouble is you would have to switch satellites to get decent programs. If your "actuator" (the gizmo that moved the dish) broke, you were out of luck. One of those cost around $150. The 2 Foot Dish: Then, the little dish came along, easier to get installed, but now you have to pay to get anything. Even if you only watch commercial TV on it, you still need to pay and the subscriptions were long term. The other problem was there were no local channels. Basic subscriptions were around $50 to $75 a month after the $300-$400 installation fee. Sometimes you have multiple subscriptions, even though you ha...
