Parachute System Control Computer

Gen 1

The PSCC-1 was the first generation of the PSCC to be tested. It used both GPS and air pressure sensors to determine it’s altitude. It was also equipped with a small LCD screen to aid in debugging, which had the unintended side effect of increasing its size. The PSCC-1 had significant accuracy issues, which contributed to the crash that destroyed it.
