Inertial Measurement Unit: This product features a built-in high-precision three-axis integrated fiber optic Gyro and a high-precision quartz flexure Accelerator. It can measure the attitude parameters of the moving carrier, including roll angle, pitch angle, angular velocity, and acceleration. The product ensures very high measurement accuracy through non-linear compensation, orthogonal compensation, temperature compensation, and Kalman filtering algorithms.
