Comprehensive the above results, the solar energy power supply design value is: battery: use lead-acid batteries, capacity of 38 ah, adopt two capacity 20 ah parallel form; Solar arrays: 25 ~ 35 w output power, USES the standard boards 25 ~ 38 w output capacity, a right.
Japanese technology giant softbank corp ( 软银) With the U. S. space agency NASA ( NASA) And the manufacturers of unmanned aerial vehicle (uav) space environment ( AeroVironment) Cooperation, build a large solar uav Hawk 30, the uav can launch 5 g signal to almost anywhere around the world.
30 is a Hawk unmanned aerial vehicle ( 无人驾驶飞行器、无人机) With 10 electronic engine, can be in more than about 20 km altitude above sea level. In addition to the information, information about the Hawk 30 fairly rare.
signed with NASA in November last year, according to softbank group of a space act agreement ( 空间行为协议) , Hawk 30 prototype may be will make its recently, the next three months will be more test mission. If all goes well, will be able to transform the wireless communications technology throughout the world.
30 is not the first try to Hawk unmanned aerial vehicle (uav) communication technology to remote areas, the space environment has developed a prototype called Helios. Helios unmanned aerial vehicle (uav) is more wide than Boeing 747, weight is lighter than a jet airliner landing gear wheels. This aircraft in 2001, at an altitude of about 2. 90000 meters altitude of more than 40 minutes, a fixed wing aircraft the world record for the longest time level flight, but in 2003 because of turbulence and the Pacific Ocean.
Facebook had made Aquila solar unmanned aerial vehicle (uav) is used to pass the network signal. Aquila plan was an experiment, in June 2017, the second test flight, Aquila prototype success at Penn, desert, 亚利桑那沙漠) Stay over nearly 2 hours. But the plan terminates in June of 2018.
in addition, Google was conducted in 2016 SkyBender plan, send 5 g network experiment to unmanned aerial vehicle (uav). But Google think use is more suitable for high altitude balloon, so the plan finally replaced by Alphabet Loon balloon plan in 2017.
so far, although with the concept of unmanned aerial vehicle (uav) to provide wireless communication attempt as a failure in the past, but that the company can learn lessons from the mistakes of the past, and try again.
