The Third Academy of China Aerospace Science and Industry Corporation proposes the construction of a flying cloud project based on a near-space solar drone to construct an aerial LAN, which can achieve long-term communication guarantees for users on the ground and the sea. Up to now, Feiyun Engineering has successfully completed multiple autonomous flight verifications, successfully carried out verification of communication applications based on space-based platforms, and achieved initial results.
Near-space solar drones are new platforms that use solar energy as the source of power and autonomously obtain energy from the outside during the flight. They can fly for several days or even months in succession. The flying height can reach near space, with high flying height and long battery life. Long, easy to use and maintain, and so on, have a "quasi-satellite" feature in a certain sense, and are the focus of current international research.
It is reported that the solar unmanned aerial vehicle developed by the Third Academy of Aerospace Science and Technology has reduced the drone's flight control difficulty while achieving high lift-drag aerodynamic performance. It adopts an ultra-light and high-strength composite body structure, which improves the wind resistance and Environmental adaptability and the use of high-efficiency energy power systems have greatly improved the mission reliability of long-duration flight of drones.
"Through the coordinated design of each sub-system, solar drones can be widely used in emergency communication support, remote sensing mapping, meteorological detection and other fields with their outstanding advantages of high flight height and long battery life, and have broad application prospects. Zhang Hongwen, president of the Third Academy of China Aerospace Science and Industry Corporation, said.
Zhang Hongwen introduced that Feiyun Engineering uses solar drones to carry air LAN communication equipment, which can provide network coverage that is much larger than ground base stations, and "adjoint" network access services that are not restricted by the area, to achieve user information interconnection in the area. It also provides transmission links for users' IP data, voice, video and other business data. It can provide effective communication network coverage solutions for areas where it is difficult to set up base stations. At the same time, it can be used under conditions of natural disasters and damaged regional communication facilities. Quickly restore communication capabilities in disaster areas.
