From the Regs. sited for GPS:
..."Designed for producing navigation results above 60,000 feet altitude and at 1,000 knots velocity or greater;...".
_AND_ in the above means the unit has to do both. The highest speed spec. I've ever seen on a consumer GPS is 999 mph (868knots); ergo, not a proscribed item on the munitions list.
