The drone, referred to as the "UAV", is a non-manned aerial vehicle operated by radio remote control equipment and self-contained program control devices. UAVs are actually the collective name of unmanned aerial vehicles. From the technical point of view, they can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft [2], unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft. , unmanned wing aircraft, etc. [3] Compared with the manned aircraft, it has the advantages of small size, low cost, convenient use, low requirements for the operational environment, and strong survivability on the battlefield. Since drones are of great significance for future air combat, major military countries around the world are stepping up their development of drones. In November 2013, the Civil Aviation Administration of China (CA) issued the Interim Provisions on the Administration of Drivers for Civil Unmanned Aerial Vehicle Systems. The China AOPA Association is responsible for the management of civil drones. According to the "Regulations", the operation of UAVs in Mainland China can be divided into 11 cases according to the size of the aircraft and the flight space. Among them, only 116 kg or more UAVs and 4600 m3 airships are operated by the Civil Aviation Authority in the integrated airspace. The rest of the flight, including the increasingly popular micro-aviation aircraft, is managed by the industry association or by the operator.

Achieve high-resolution image acquisition

The UAV can realize the acquisition of high-resolution images. While making up for the shortcomings of satellite remote sensing, which often cannot obtain images due to cloud occlusion, it solves the problems of long period of traditional satellite remote sensing revisiting and untimely response.

Unmanned fighter

The drone system consists of an aircraft platform system, an information acquisition system, and a ground control system.

The original generation was dominated by reconnaissance aircraft, and some drones were already equipped with weapons (such as the RQ-1 Predator equipped with the AGM-114 Hellfire-to-Earth missile). The military anticipation of more roles by drones was initially bombing and ground attack, air-to-air combat, and the final area of ​​the pilot. UAVs equipped with weapons are known as unmanned combat aircraft (UCAV).

Launch and recycle

A new generation of drones can be launched and reclaimed from a variety of platforms, such as ground vehicles, ships, aircraft, suborbital aircraft and satellites. The ground operator can verify its program through a computer and change the heading of the drone as needed. Other more advanced technical equipment, such as advanced eavesdropping devices, radar penetrating the leaves, and micro-spectrometer devices that provide chemical capabilities, will also be installed on drones.

(1) Start interface: Quickly realize the planning of tasks, enter the task monitoring interface, realize fast and automatic archiving of aerial tasks, and divide each function to realize the specific and stable operation of the software.

(2) Pre-flight inspection: In order to ensure the safety of the mission, the flight control software is automatically detected before take-off to ensure that the aircraft's GPS, compass, airspeed tube and its tilting are in good condition, avoiding dangerous situations in aerial photography. .

(3) Flight mission planning: The planning of flight missions is carried out in three modes: regional aerial photography, navigation and hybrid.

(4) Aerial flight monitoring: Real-time grasp of the aircraft's attitude, azimuth, airspeed, position, battery voltage, instantaneous wind speed and direction, mission time and other important states, which is convenient for the operator to judge the executableness of the task in real time and further ensure the safety of the mission.

(5) Image stitching: After the aerial photographing task is completed, the aerial image is navigated to perform image stitching in the study area.
