Ok, let's try to keep this civil. Most artificial satellites orbit the earth at a low enough orbit that they "move" across the sky relative to a ground observer. If you wait until about an hour after sunset, once the sky is dark and the stars are visible, you can see many of these lazily travelling across the sky (since the sun hasn't set for them yet, because of their altitude). These satellites orbit the earth many times per day, and GPS and Spy satellites are two examples of these.
But if you increase your orbital altitude, based on the law of gravity, you will reach a point where "one orbit" around the planet is 24 hours. If you're careful with your launch vectors and burn times, you can "insert" a satellite into Geostationary orbit, also called geosyncronous, because it "keeps the same time" as the earth's rotation. By definition, these orbits lie in the plane of the equator, which is why everyone's dishes are pointed south, in the northern hemisphere. TV (like DirecTV), Radio (like XM and Sirius), and Weather satellites are examples of these.
http://en.wikipedia.org/wiki/Geostationary_orbithttp://www.sea-launch.com/past_launches.htmIt uses a lot less fuel (which means you can launch a bigger payload), if you can launch from the Equator, which is exactly what the SeaLaunch platform does. They took a converted oil drilling platform and built a rocket launchpad, and they've launched a bunch of satellites from sea.
Years ago, the only geosyncronous satellites that everyday citizens cared about were various telecommunications satellites operated by TV and Cable networks (that's how they get their signal from one side of the country to the other, since copper wire is too slow and TV and Radio waves are too weak). So people installed
large satellite dishes on their homes (it was pretty expensive), and these dishes had to be aimable, since they needed to pick up signals from any of a number of different networks' satellites.
But now that we have DirecTV and the Dish Network (to name two here in the US), the whole point is to broadcast a signal to consumers, so the dish is carefully aimed only once, then bolted in place. The dish is also much smaller since the signal is stronger. These tiny dishes, even if they were equipped with transmitters, would be unable to send much of a signal.
Satellite radio, being that it's the most modern of the technologies discussed here, broadcasts to small omnidirectional antennas which people mount on their cars and such. Stereo radio has much smaller bandwidth than a TV broadcast, which makes such a tiny receiver antenna possible.
All of this is neatly explained because we live on a globe, and gravity exists so we can have satellites orbit it. Any evidence the the contrary, other than a few links to
pseudosatellites (ground-based radio repeaters) and
stratellites (high-altitude balloons, still in the prototype phase)?
