This IMU module integrates high-precision gyroscopes, accelerometers, and geomagnetic field sensors. It uses high-performance microprocessors and integrates an attitude solver which cooperates with the dynamic Kalman filter algorithm to accurately output the current attitude in dynamic environment.
It has the advantages of excellent noise immunity, no hysteresis, and stable temperature characteristics. The attitude measurement accuracy is statically 0.001°, the stability is extremely high and the performance is even better than some expensive and professional IMUs.
The Z-axis heading angle is added to the geomagnetic sensor filter fusion, which solves the cumulative error caused by the drift of the gyroscope integral in the 6-axis algorithm, and can output heading angle data stably for a long time. IP67 level protection, aluminum shell, strong resistance to external electromagnetic interference, stable performance, and can adapt to long-term work in harsh industrial environments.
