Your GPS Will Disable Itself If It’s Going Too Fast

Whether it’s your windshield mounted Garmin or your pocket slung smartphone, your GPS device is programmed to disable itself under certain conditions.
If it’s travelling faster than 1200 MPH or above 65,000 feet in altitude, the GPS function will shutdown.
These restrictions were put in place to help ensure the technology could not be used for malicious intentions by foreign governments or terrorists.
Modern commercial airplanes do not typically approach this speed or altitude, so you can’t test this unless you build your own missile or weather balloon.
