The two companies has successfully performed numerous stratospheric flights with the autonomous HiDRON unmanned glidar.
For the first two launched, the HiDRON UAV was launched from a balloon at an altitude of 25 km, then at 30 km for the final launch. The HiDRON glided in a controlled path back toward Spaceport America’s runway for 4.5 hours.
During the mission, the aircraft took measurements and recorded navigation data on a flight recorder with a frequency of up to 400 Hz. Using onboard sensors, the stratospheric UAV recorded wind velocity, direction, magnitude and low-frequency sound waves. This data can be useful when analyzing atmospheric phenomena in the stratosphere.
