During the flight process, its position and posture (including roll, pitch and yaw) are the important control factors, and this information must be measured accurately. Where GNSS is used to measure position, and inertial navigation is used to measure attitude information. Although GNSS is a conventional method of UAV positioning, in some special cases, such as when the GNSS signal is blocked or disturbed, inertial navigation can play an important auxiliary role and calculate the position and speed of the UAV by the integration of acceleration and angular speed. The inertial navigation system is mainly composed of an accelerometer and a gyroscope, which can measure the acceleration of the UAV in three axial directions (usually x, y, z axis), and the gyroscope is used to measure the angular rate of the UAV. By integrating the measurement data and solving the attitude information of the UAV can be obtained.
