Yes. Some GPS brands stop working between 32000 and 40000 feet. There was a rule that said a consumer GPS can not work above something like 32000 feet or above a certain speed. It was to prevent cheep GPS units to work on enemy missiles. Some manufacturers read it as a certain height OR a certain speed, not AND. I prefer the UBlox GPS because it has modes you can set with their configuration program. (Free download) Aircraft 1 mode is for a slower aircraft. Still faster than a balloon but the slowest of the aircraft modes. I have had it up to 132,000 feet. It comes with automobile mode as default, so you have to change it. None will work over a certain height. I think it is 160,000 feet. Again because of military rules. Kip
