Yes, the BigRedBee transmitter uses a Trimble Lassen IQ chipset which has been previously flight tested to altitudes above 100,000 feet. There are more pictures and data of flights like this here:
The GPS module I use in the BeeLine GPS transmitter does indeed work above 18000 meters. It's only when it's above 18000 meters AND 515 m/s that it cuts out -- but we haven't test that yet ;) It's been part of payloads in high altitude weather balloons to higher than 100,000 feet MSL.
Weight of the GPS module transmitter with battery is just 55g, the FM beacon is 20g
Good luck Steve!
