There are currently 32 GPS satellites Orbiting earth at 20,000Kms above sea level
There are also 24 GLONASS satellites (The russian version of a GPS satellite) Which many high end GPS receivers will use in conjunction with the standard GPS satellites. These orbit a little lower than GPS at arond 19,000Kms above sea level.
There are 4 Galileo Satellites, which are currently un used, but are the start of the European satellite constealltion which is a work in progress. They orbit at 24,000Kms above sea level.
On top of all that, there are 10 Chinese navigation satellites called COMPASS orbiting in an orbit above China and Asia. They orbit at around 21,000 Kms above sea level.
there is no satellites orbiting Saturn
There are thousands of satellites in Earth's orbit, with estimates ranging from 2,200 to over 3,000 active satellites. Additionally, there are many more inactive or defunct satellites and debris in orbit.

Communication satellites are lifted into orbit by rockets.
Satellites cannot orbit the US; they orbit the Earth, and there are several thousand of them.
The satellites are usually placed so in an orbit high enough so that they don't lose much movement energy due to atmospheric friction.
Because satellites can't stay in orbit if they're moving through air, so they have to be high enough where there's no air.
a lot
