How does an artificial satellite remain in orbit at a constant distance from

Earth's surface?
well how would a regular satellite remain in orbit?

The same way a 'non' artificial satellite remains in orbit at a constant distance from Earth's surface...

any finite mass can be made to orbit earth at a constant distance away, given it has the 'appropriate' tangential velocity. It's a simple calculation. The difficult part is getting the satellite there...
