The UAV is mainly composed of three parts: the flight carrier, the flight control system, and the mounting mechanism. The flight control system is used to complete the flight carrier to drive and fly according to the predetermined route. The IMU and integrated navigation products developed by our company can provide the UAV control system with three-axis attitude parameter data of heading, pitch and roll, as well as parameter data such as horizontal position, vertical position, and XYZ three-direction velocity and acceleration, helping the flight control system to realize the control and adjustment of aircraft flight status.
