How drones work

A typical unmanned aircraft is made of lightweight composite materials to reduce weight and improve maneuverability. The strength of this composite material allows military drones to sail at extremely high altitudes. The engineering materials used to make drones are highly complex composite materials designed to absorb vibrations and thereby reduce the sound produced. These materials are very light.

UAVs are equipped with technical devices with different functions, such as thermal imaging cameras, GPS and lasers (consumer, commercial and military UAVs). The drone is controlled by the remote ground control system (GSC), also known as the ground cockpit.

The UAV system consists of two parts: the UAV itself and the control system.

The nose of the drone is where all the sensors and navigation systems are located. The human body part is full of drone technology systems, because the drone does not need any space to carry humans.
Radar positioning and return

The latest UAV has dual global navigation satellite systems (GNSS) such as GPS and GLONASS, and the most recent UAV is equipped with China’s Beidou navigation. The drone can fly in GNSS mode and non-satellite mode.
Obstacle detection and collision avoidance technology

The latest high-tech drones are now equipped with collision avoidance systems. They use obstacle detection sensors to scan the surrounding environment, while software algorithms and SLAM technology generate images into 3D maps so that drones can sense and avoid them. These systems fuse one or more of the following sensors to sense and avoid.
Gyro stabilization, IMU and flight controller

The gyroscope stabilization technology enables the drone to have a stable flight capability. The gyroscope acts almost immediately against the force of the drone, keeping it flying or hovering smoothly. The gyroscope provides the necessary navigation information for the central flight controller.

GPS ready flight mode drone technology

After the compass is calibrated, it will look for the location of the GPS satellites. When more than 6 are found, it will make the drone fly in “ready to fly” mode.

Internal compass and fail-safe function

Make UAV and remote control system know its flight position accurately. If the drone and the remote control system stop connecting, you can set the home point, which is the location where the drone will return. This is also called a “fail-safe function”.
