High-precision digital micro-inertial navigation system

BW-MINS600 is an ultra-high-precision micro-mechanical electromechanical inertial navigation system developed and produced by Bewis. Without relying on external signal input, it can automatically calculate the azimuth and horizontal angle of the measured carrier through acceleration and angular velocity information. Roll angle, pitch angle, angular velocity, acceleration, Euler angle, quaternion information, suitable for inertial attitude measurement under various states of motion, vibration or static. BW-MINS600 uses highly reliable MEMS accelerometers and gyroscopes. The attitude information data deviation is estimated by the 6-state Kalman filter with appropriate gain, and the measurement accuracy is ensured by the algorithm. The attitude motion parameters are nonlinearly compensated and orthogonal. Compensation, temperature compensation and drift compensation, etc., can greatly eliminate errors and improve product accuracy. This product has a digital interface, which can be easily integrated into the system.
