UAVOS and STRATODYNAMICS HiDRON stratospheric glider Sets New Canadian Record Achieved At Over 111,400 Feet Altitude

As a part of the joint project between UAVOS and STRATODYNAMICS, UAVOS is excited to announce their latest successful record-setting stratospheric flight. The stratospheric glider named the HiDRON was released from a Canadian Space Agency scientific gondola at an altitude of 111,434 feet (33.9 km) and performed a four hour controlled flight and landed at Iroquois Falls Airport about 80 km from the Timmins, Ontario launch site. The flight once again confirmed the HiDRON's capability to perform high-altitude missions and beyond visual line of sight (BVLOS) operations and set a new operational best for the flight in a challenging stratospheric environment.

The night flight demonstrated the HiDRON’s beyond visual line of sight (BVLOS) capabilities and was supported by the Canadian Space Agency (CSA) and the French Space Agency (CNES) as part of the 2019 Strato-Science Balloon campaign at the balloon base in Timmins, Ontario.

The record setting flight achieved many firsts in Canadian Aviation:

• Highest altitude flight of a UAV or Remotely Piloted Aerial Systems (RPAS). RPAS is the name used by Transport Canada to encompass UAVs.
• First UAV above 29,000 feet in Class A airspace.
• First release of a UAV from a scientific gondola in Canada.

The HiDRON release from the CSA gondola is another first for the companies, as previous launches have been carried out by weather balloons, and added new layers of complexity. Prior to the launch, the Stratodynamics and UAVOS teams advanced aspects of the HiDRON including the transponder, stratospheric flight controls, data links, and safety protocols. The HiDRON features UAVOS’ autopilot AP 10.3 Micro.

The HiDRON was launched from the Timmins Victor M. Power Airport via the CSA scientific gondola at 10 pm on Saturday, August 31st. The mission plan was to release the HiDRON from the gondola sometime between an altitude of 30 km altitude and the target ceiling altitude of 37 km (121,000 feet). Once released the HiDRON would follow a pre-set flight plan and land at Iroquois Falls Airport. This meant the team was onsite at the Timmins airport until the gondola’s lift-off from the CSA Balloon Base.

As the gondola rose to its float altitude, the HiDRON was released at around 12:30 am on September 1st at an altitude of 111,400 feet. The HiDRON performed well in difficult headwinds and -60° C stratospheric conditions with its AMON detector recording single pixel data in a near-moonless night sky.

The record setting flight is the culmination of 12 months of international collaboration and planning with colleagues in Canada, Belarus and Slovakia and was the second of two flights commissioned to test AMON Airglow detector from Stratodynamics’ client, the Institute of Experimental Physics at the Slovak Academy of Science. The Slovakian team was searching for a cost-effective method for the AMON detector to have a clear view upwards unencumbered by a weather balloon blocking the view. The AMON detector is planned to participate in EUSO-SPB2 mission that will fly on a long duration NASA balloon in 2022.
