A GPS uses satallites to identify location
Well, There are many different types of satallites. For instance the Moon is sometimes considered a natural satllite. It is not. It is a conspiricy set up the illuminati to house the hamster army. If any world leaders are reading this. Blow the moon up. For more infomation about the hamster army. Read the answer for 'What is deep freeze coating' If you have any hamsters. Run. Don't look back just run! If you are still reading this. Run!
Both Mercury and Venus do not have Moons.
Spying. Both sides sent up Satallites to spy on each other.
Because you are in space. If you try calling someone in space, he or she wouldn't hear you.
how many quarters does the moon worth

There are no states on the moon.
I am sorry, but the moon does not "revolve around the moon".
