The principle of the UAV control system

Drone technology features:

　　Realize the acquisition of relatively resolution images

　　UAVs can realize the acquisition of relatively resolution images. While making up for the shortcomings of satellite remote sensing often not being able to obtain images due to cloud occlusion, it solves the problems of traditional satellite remote sensing revisiting cycles that are too long and timely emergency responses.

Unmanned fighter

The UAV system consists of an aircraft platform system, an information collection system and a ground control system. The early generations mainly focus on reconnaissance aircraft, and some drones have been equipped with weapons (e.g.RQ-1Predator EquipmentAGM-114Hellfire air-to-ground missile). The military expectation of more roles by drones is initially bombing and ground attacks, air-to-air combat, and pilots are in the latter area. Weapon-equipped drones are called unmanned fighter aircraft (Ucav）。

Launch and Recycling

The new generation of drones can be launched and recycled from a variety of platforms, such as launching and recycling from ground vehicles, ships, aircraft, suborbital vehicles and satellites. The ground operator can check its procedures through a computer and change the course of the drone as needed. Other more advanced technical equipment, such as relatively-level eavesdropping devices, radars that penetrate leaves, micro spectrometer devices that provide chemical capabilities, will also be installed on the drone.

Drone workflow:

（1) Start interface: Quickly implement task planning, enter the task monitoring interface, realize quick and automatic archiving of aerial photography tasks, separate various functions, and realize the dedicated and stable software operation.

（2) Pre-flight inspection: For the safety of the mission, automatic detection is carried out in combination with flight control software before takeoff, for the aircraftGPS, compass, airspeed tubes and pitch rolling are in good condition, avoiding dangerous situations in aerial photography.

（3) Flight mission planning: Planning of flight missions in three modes: area airlighting, navigation, and hybrid.

（4) Aerial flight monitoring: Real-time mastery of the aircraft's attitude, orientation, airspeed, position, battery voltage, real-time wind speed and direction, task time and other important states, so that operators can judge the executability of the task in real time, and further for the safety of the task.

（5) Image stitching: After the aerial photography mission is completed, navigate the aerial photography images to perform image stitching in the study area.
