China’s solar-powered, semi-satellite drone

China’s first fully solar-powered unmanned aerial vehicle has successfully completed its maiden test flight with all on-board systems functioning optimally.

About the new machine

• The drone is a large machine powered entirely by solar panels.
• It has a wingspan of 164-ft.
• The high-altitude, long-endurance (HALE) UAV can stay airborne for long durations.
• It is named as the Qimingxing-50, or Morning Star-5.
• This drone flies above 20-km altitude where there is stable airflow with no clouds.
• This helps these drones to make the maximum use of solar equipment to stay functional for extended durations.
• In fact, the drone’s chief designer told South China Morning Post that it can operate without a break for months, even years.
  
  
• It is capable of carrying out satellite-like functions.
• If satellite services are not available for, say, time-sensitive operations or in case of wartime disruption, then near-space UAVs can step in to fill the operational gap.
• These drones are also referred to as ‘High Altitude Platform Stations’ or pseudo-satellites.
• China already has this capacity, but the Qimingxing-50’s long-endurance provides an added advantage to make this capability available over a longer period.
