Solar drones build airborne LAN to achieve phased results
According to Xinhua News Agency, Beijing, March 18 (Reporter Hu Wei), the reporter recently learned from the China Academy of Aeronautics and Astronautics Group Third Hospital that the institute proposed a flying cloud project based on the adjacent space solar drone to build an airborne LAN, which can achieve A long-term communication guarantee for a wide range of users on the surface. Up to now, Feiyun Engineering has successfully completed multi-station autonomous flight verification, successfully carried out communication application verification based on space-based platform, and achieved phased results.
The adjacent space solar drone is a new type of platform that uses solar energy as its power source, autonomously obtains energy from the outside during flight, and can fly continuously for several days or even months. The flying altitude can reach the adjacent space, with high flying height and long battery life. The characteristics of long, easy to use and maintain, and in a certain sense have the characteristics of “quasi-satellite”, which is a hot spot in current international research.
It is reported that the solar drone developed by the Third Academy of Aerospace Science and Technology has reduced the flight control difficulty of the UAV while achieving high lift-to-drag ratio aerodynamic performance. The ultra-light high-strength composite material structure has been adopted to enhance the wind resistance of the UAV. Environmental adaptability, the use of high-efficiency energy power system, greatly enhance the mission reliability of the long-haul flight of the drone.
“Through the matching and coordination design of each subsystem, the solar drone can be widely used in emergency communication support, remote sensing mapping, meteorological detection and many other fields with its outstanding flying height and long life time. It has broad application prospects. Zhang Hongwen, dean of the Third Academy of China Aerospace Science and Industry Corporation, said.
Zhang Hongwen introduced that Feiyun Engineering uses solar-powered UAVs to carry over-the-air LAN communication equipment, which can provide network coverage that is much larger than that of terrestrial base stations and “concomitant” network access services that are not restricted by the area, so as to realize inter-regional user information interconnection. It also provides transmission links for user data such as IP data, voice, and video; it can provide an effective communication network coverage solution for areas where it is difficult to set up a base station, and can also be in the condition of natural disasters and regional communication facilities being damaged. Quickly restore communication capabilities in disaster areas.
