It has a built-in high-precision three-axis fiber optic gyroscope and accelerometer. It can output acceleration and angular velocity information without relying on external signal input. The user can calculate the azimuth angle, roll angle, and pitch angle of the measured carrier, which is suitable for inertial measurement in various states of motion, vibration or static. BW-IMU900 uses a highly reliable MEMS accelerometer and a three-axis fiber optic gyroscope. The original data deviation is estimated by the 6-state Kalman filter with appropriate gain, and the measurement accuracy is ensured by the algorithm. The parameters are compensated by non-linearity and orthogonality.
