New Technology

During the 2015 Nepal Earthquake, a Prodrone drone was used to survey damages.
This was the first time in the world that a drone was used at altitudes greater than 5500m for three-dimensional surveying!

In the April 2015 Nepal Earthquake, PRODRONE was part of the emergency survey team sent to Langtang Valley, one of the areas hit worst by the earthquake. PRODRONE also designed, developed, and donated special drone attachments for the emergency survey team.

* Nepal Emergency Survey Team: Nagoya University, Tokyo Metropolitan University, and Institute for Earth Science and Disaster Prevention were also on this team.

Specifications of the donated drones

  • ・An airframe developed specifically for high altitude flight. These were designed to be extremely light, extremely powerful, and foldable.
  • ・Capable of high-altitude flight at 5500m or higher for longer than 15 minutes.
  • ・New model motors and control unit developed by DJI.
  • ・A full-size DSLR camera with 2cm precision.

Mission details

  • Lift-off from an elevation of 5115m, then climbed to approximately 5500m, and concluded aerial investigation for 15 min. 45 sec.
  • Lift-off from an elevation of 3500m, then climbed to 4500m, and surveyed upper part of the valley.
The mission was conducted at a record setting altitude for high-precision photographic survey using multicopter drones. (As of 2015, according to our investigation.)
The high-precision photographic information will be analyzed by the research team for disaster research and relief plans in the Lantang Valley.

Thanks to the drones, we could obtain highly-precise data that would have been previously impossible. Through the use of this photographic data, we hope to determine the cause of the avalanche, as well as the extent of the damages. When the villagers begin to rebuild, I would like to suggest the safest places for their houses.

Seeing that the drone could fly beyond an altitude of 5500m and still have power to give while remaining stable, I knew the doors had been opened to the possibilities for it to serve in disaster research and surveying at altitude higher than 6000m.
