Ublox SAM-M8Q

Yes it should work, I beleive its just a MAXM8Q Ublox device with added ceramic patch.

The MAXM8Q is a popular GPS for high altitude ballooning, at least it is in the UK.

Most GPS will work only up to 18,000M, the MAXM8Q is one of the few that can be configured to operate up to 50,000M.
