An Altitude Control System for Flight Control and Stability of HAB Missions

Our Altitude Control System (ACS) is a flight control system for latex high-altitude balloon (HAB) missions designed to allow controlled venting of helium. In the absence of any mechanism to vent helium, a typical latex HAB will rise at a relatively constant rate until it reaches burst altitude. Our ACS is designed to vent helium at a desired altitude utilizing COTS products and some 3D-printed parts. The ACS was developed to extend flight time at a target altitude for imaging and to expand the scientific research potential for latex HAB missions.
