Overview
1. The module integrates high-precision gyroscopes, accelerometers, and geomagnetic field sensors, and uses high-performance microprocessors and advanced dynamics calculation and Kalman dynamic filtering algorithms to quickly solve the current real-time motion posture of the module.
2. Using advanced digital filtering technology, it can effectively reduce measurement noise and improve measurement accuracy.
3. An attitude solver is integrated inside the module, and combined with the dynamic Kalman filter algorithm, it can accurately output the current attitude of the module in a dynamic environment. The attitude measurement accuracy is 0.2°, the stability is extremely high, and the performance is even better than some professional inclination angles. instrument.
4. 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.
