Zephyr Solar UAV Operates 11 Days in Winter Conditions

Airbus’ Zephyr 7 solar-powered UAV has recorded an 11-day, non-stop flight in winter weather conditions, the company said Thursday.
The flight of the High Altitude Pseudo-Satellite (HAPS) system was undertaken in the last few weeks for the British Ministry of Defence while carrying a new, but unspecified, primary payload.
Airbus Defence and Space wouldn’t say where or when the test flight of the Zephyr 7 took place but did say the machine flew from a base in the Southern Hemisphere.
The Zephyr 7 flew at altitudes of up to 70,000 feet and for the first time used satellite communications to control and monitor the flight beyond line of sight of the ground station.
