How Satellites Work

Geostationary satellites are positioned one-tenth of the way to the moon (about 36,000 km), but how do they stay there? This video shows how satellites stay in orbit.

I love youtube!

Just finished doing work experience at EADS Astrium. Something that blew my mind was the money.

1 satellite, from start to space, costs around £1,100,000,000. 1.1 billion!

Eveything is so expensive! It's like £10 for an inch of mirroring, £17 for an inch of pipe. £300,000 for 1 tank. £20,000 for every kilogram it ways.... just mind blowing at the costs... but the revenue... jees

The Moon isn't in a 'permanate' orbit.. its actually moving away from the earth about 3 inches each year

Затянутое, но интересное видео от европейского спутникового оператора

nice video.....very knowledgeable.

wow super cool (^_^o)

Nice graphics, you can also download a Google Earth file that shows all the satellites currently in orbit at the O3B network website.

How could it be 'set free' ? If it is simply not in use the satellite will slowly move out of its orbit (which is why the thrusters are used to keep the satellite on track) and the centrifugal force which you suggest doesn't exist, has an effect on the satellite in which it's orbit increases in distance from the earth as the speed of a moving object on a curved axis encourages it to move outwards...when the centrifugal force is equal to the gravitational pull, the satellite stays in orbit.

There is no such thing as a "centrifugal" force. Neither would the satellite fly backwards from the Earth if "set free" - it would go off in a straight line at a tangent to the original direction of travel. Shame about the poor physics in an otherwise good video.

Nice... satellite transmission now and what we have next in store for us? Like in startrek, subspace communication that could bend laws of physics? Possibilities are endless so as long us humans can stay innovated.
