What is a drone? Hello, I’m glad to answer for you. Unmanned aerial vehicle (UAV) is an unmanned aerial vehicle operated by radio remote control equipment or its own program control device. From the technical point of view, it can be divided into unmanned helicopter, unmanned fixed-wing aircraft, unmanned multi-rotor aircraft, unmanned airship and unmanned para-wing aircraft. UAV has many advantages, such as wide use, low cost, good cost-effectiveness ratio, no risk of casualties, strong survivability, good maneuverability and easy to use. It plays an extremely important role in modern warfare and has a broad prospect in the civilian field. Unmanned aerial vehicles (UAVs) are divided into reconnaissance aircraft and target aircraft. In the military field: Reconnaissance aircraft: It can be used for battlefield reconnaissance and surveillance, positioning and firing, damage assessment, electronic warfare, etc.; Target drone: It can be used as a target for artillery and missiles. As far as the military field is concerned, Western countries led by the United States have played a very good role in the use of UAVs. In the civil field, it can be used for mapping, geological survey, disaster monitoring, meteorological detection, air traffic control, border patrol monitoring, communication relay, pesticide spraying, etc. Like Kunming Jinying UAV, it has done well in aerial survey, aerial photography, flight service, remote sensing and so on. I hope my answer can help you. UAVs: How they are used During travel, more and more people begin to carry drones for travel photography. Every country and region has a no-fly rule for drones. When taking travel photography, you must be familiar with the no-fly rules of each region. Exploiting innovation and finding unique perspectives can create interesting, fresh, and engaging images and videos, and drone photography is a new way to discover the world around us. Looking down from the sky, all the scenes and places become fresh and fascinating, and it is an exciting pleasure and a great challenge to enter UAV photography. Improper operation or interference are easy to “blow up” the situation, it must be noted that the explosion is not the UAV, but your blood, blood, blood. Money, money, money! Every takeoff is actually a parting of life and death! You can have super high operating skills, but you can’t control the occurrence of other factors. During the last flight along the Sichuan-Tibet line, after about 10 seconds of video recording, the signal was interrupted and the drone “exploded”. At that time, Xiaobian’s heart also fell into the surging river with the drone. In fact, at the beginning, all the novices were blown up by the plane. In addition to human factors, there are many uncontrollable factors in flight technology.
