Not at all. The mutual gravitational force that attracts the satellite and the earth toward each other is exactly what keeps the satellite in orbit. Without it, the satellite would just take off in a straight line away from the vicinity of the earth.
Satellite speakers are usually part of a surround sound system. Then can be placed on stand or can be wall mounted. They're placed around a room at direct points and only play certain sounds to create the surround effect.

Doesn't work like that, a satellite can't orbit one country. It can stay in geostationary orbit over some, but that's it. Sputnik 1 orbited the whole Earth.
No, the cable will not work when the satellite is out. The satellite is what brings you the picture. If you are concerned about the satellite, I would stay with cable.
Staying at the "same point" (i.e., above the same location on Earth) is onlyimportant for a Geosynchronous satellite, which must occupy a very high orbit.Most satellites (and the International Space Station) are in lower orbits, whichmeans they orbit the Earth faster than it rotates, so they don't stay in thesame place.===================================Answer #1:Now to deal with the question . . .If the satellite is going to be used by non-technical people with little 'dishes'on the corner of their house or garage, it's important that they not need tomove their dish to follow the satellite across the sky. If people couldn't "setit and forget it", there would be no Dish network or Direct TV or any of theothers, because very few customers would be willing to do what it takes tokeep their dish tracking the satellite. Sure it could be automated, with amotorized mechanism that constantly steers the dish to follow the satellite.But that would cost 20 times what those dinky dishes cost now, and again,the operators would not "have a business". The only way that this wholescheme of satellite-direct-to-the-home can work is to make the satellitemotionless in the sky. The installer comes to your house, mounts the dish,'finds' the satellite, points the dish in that direction, and locks it permanentlyin that position. That's the only way the business model can work.

The operational Frame work describes the overall structure of your work. For example is your work is related to routing protocols then the operational famework may be the mobility models, network configurations, resource distributions etc.
it depends on where the satellite is. if the satellite is close, it will work
It means that everything that is supposed to work does work
Satellite phones work by connecting directly to a communications satellite in orbit, which then routes the call to a standard phone network. Because the satellites are in orbit the phone can work anywhere on earth.
It sends a signal directly to the satellite and the satellite pinpoints the location of it.
