Ok I'll stop my amateur speculation right now before it gets completely out of hand ^_^ Godspeed and best wishes to all of you.

One of them is a veteran of 12 runs to over 100,000 feet. They both failed just over 20,000 feet and came back at just over 60,000 feet. They recovered when the temperature was at a minimum. It's pretty baffling. JP Both GPSs are without the altitude limitations. One of them is a veteran of 12 runs to over 100,000 feet.

I can't vouch for the following but according to some the civilian GPS receivers have a combination of two limitations specific to your use where it shuts down somewhere above 18 km if it travels faster (or possibly slower?) than some limit (I don't remember what it was). There's supposed to be ways to get around it but I have no idea if it's true and/or practical for you to do so or if this is even part of the problem you're facing.
