Yes, the satellites orbit in a geosynchronous orbit, as with most all communications satellites. (Some exceptions are satellites such as the global positioning satellites.)
Most communications satellites operate outside of the earth's atmosphere. The GPS satellites are about 23,000 miles from the surface of the earth.
Geosynchronous orbit? or Low Earth Orbit?
With large number of low-earth-orbit satellites and the geo-synchronous orbit stuffed full of communications satellites, there aren't all THAT many "medium" altitude satellites. But there are some. The GPS navigation satellites, for example, are in highly inclined 12-hour orbits, and an unknown number of military "spy" satellites are in that middle range.
In an age of geocentric satellites, the moon's orbit would preclude its reliability. However, the moon was used as a type of 'communications sat' back in the 50s, and modern-day satellites grew from that program. See link.
Communication satellites are lifted into orbit by rockets.
No, all satellites do not orbit Earth at the same altitude. An good overview of this can be found on http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx. This overview reviews Low Earth Orbit, Medium Earth Orbit and Geostationary Orbits.
That depends on the altitude. Low altitude satellites, about 140 miles up, take about 90 minutes to orbit. Communications satellites 23,000 miles up take 24 hours. The higher the orbit, the longer it takes.
Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.
The tv satellites orbit called is a geo stationery.
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.
