Which key sensors
in UAVs and what types of sensors are used in UAVs, inertial measurement units are the core sensors used in UAV sensors, and are basically micro-electromechanical systems (MEMS), which are very important in the semiconductor industry The first branch. The MEMS inertial sensor, which is based on semiconductor manufacturing skills, has been developed on a large scale since 2011. 6-axis and 9-axis inertial sensors have gradually replaced single sensors.
Now on cost-grade unmanned aerial vehicles, inertial measurement unit contact GPS is the key to maintain the direction and flight path. With the intelligent development of drones, direction and approach control are the primary air traffic management rules. The multi-axis magnetic sensor used in the inertial measurement unit is essentially a small compass with extremely high accuracy, transmits the data to the central processor after sensing the direction, and then indicates the direction and speed.
Acceleration sensors-what types of sensors are behind the drone? We know that many types of sensors are installed on the body of military drones. Accelerators can be used to sense linear acceleration and skewed viewpoint. Single or multi-axis accelerators can sense the relationship between linear and gravitational acceleration. The amplitude and direction are the foundation of the flight control system. During this period, the acceleration sensor is the standard configuration of many drones. It is mainly used to determine the orientation and the flying posture of the drone, which plays a vital role in maintaining the flying control of the drone. MEMS acceleration sensors have a variety of methods to sense movement posture, and can sense the tiny movements of micro-integrated circuits. This type of movement alters the movement of current in the structure and then indicates changes in displacement associated with gravity.
Electronic compass-what types of sensors are on the UAV after the UAV, the electronic compass is mainly used to provide vital inertial navigation and direction positioning system information. The electronic compass can sense the direction from the earth's magnetic field. The use of costly electronic goods using the electronic compass includes displaying the correct direction on the map use program of the mobile phone, or providing the forward direction data for the navigation use program.
