The Limits of GPS Regulations

GPS device will not work on the moon because it will be deliberately capped to turn off above 18 kilometers. If you could find a manufacturer who's a little bit more liberal with the international multi-lateral export controls, as long as you could get it to the moon without going faster than 1,000 knots,. But the moon moves quite fast. It gets all the way around the earth every 27.32 days, which means the moon is actually moving at 3,832 kilometers per hour. So in theory, if it worked, it would work. But because it doesn't work, it won't work.
