With a wingspan of 45 meters, the solar-powered drone is capable of flying at an altitude of 20 to 30 kilometers, and cruising at a speed of 150 to 200 km per hour for a long time. The unmanned aerial vehicle will be used mostly for airborne early warning, aerial reconnaissance, disaster monitoring, meteorological observation and communications relay. [Photo/CCTV]

It has taken over one year to solve the issue of precise control in complicated weather conditions to ensure more reliable flight.

"With the development of the CH UAV, new technologies and products such as graphene-related materials, advanced solar cells and innovative energy storage methods will also be developed and these will further promote China's aviation industry," Shi said.
