GPS devices receive signals from several Global Positioning Satellites, which orbit the earth. The device uses the difference in timing from the signals to calculate its own position. I don't remember, but I think you can get a position with signals from 4 satellites, so you would need to have a clear signal from the satellites in order for the device to calculate its position.

A GPS will work anywhere it can receive adequate signals, and assuming you have a decent antenna, any GPS will work in an airplane.
