1 # What altitude limits exist for the GPS receivers on Altus Metrum products?
3 The U-blox parts we use perform well in airborne mode, and are the gold
4 standard for hobby rockets. However, series 8 and below reportedly stop
5 reporting above 50km altitude, and series 10 stops reporting above
6 80km. We do not have flight data from anyone who's gone that high to confirm
7 or deny this, though others report confirming it with GNSS simulation systems.
