AI Overview
Consumer GPS devices are designed to stop working at speeds exceeding 1,200 mph (approx. 1,900 km/h or 1,000 knots). This restriction, often called COCOM limits, is implemented to prevent GPS from being used in ballistic missiles. Additionally, many devices shut down if they exceed an altitude of 60,000 feet (approx. 18,000 meters).

What speed does GPS turn off?
Only kind of relevant, but I remember reading on Reddit that if a GPS is going over 1,000 MPH it, by law, must shut off because it is likely guiding a missile. So to narrow down your speed window (assuming the above is true), a GPS is able to track at over 1,000 MPH.Oct 9, 2011
