Purpose Built for the Stratosphere

The HiDRON is a unique balloon-launched unmanned glider capable of high-altitude flight; autonomous and soaring flight modes; and operates well in the cold stratospheric environment (-60┬░ C).

Once the balloon reaches the target altitude, the HiDRON is released and glides in a controlled descent. The return flight  back to home can be altered in real-time by the operator at the ground station and landing is automatic.

HiDRON Flight graphic controlled descent

We custom integrate instruments within HiDRON power supply, sensors, telemetry, and component heating systems. Data is transmitted in real-time to the ground station and collected. The data set is time-stamped to 10 Hz, collated with GPS location and can be combined with over 200 parameters from the flight mission and other onboard sensors and video images.
