Overview
This module seamlessly integrates highly precise gyroscopes, accelerometers, and geomagnetic field sensors, utilizing cutting-edge microprocessors and advanced dynamics calculation alongside Kalman dynamic filtering algorithms to swiftly determine the present real-time motion posture of the module.
By leveraging sophisticated digital filtering technology, this sensor effectively mitigates measurement noise, thereby augmenting measurement precision significantly.
Equipped with an embedded attitude solver, this module, in conjunction with the dynamic Kalman filter algorithm, adeptly delivers the current attitude of the module in dynamic settings with remarkable precision. With an exceptional attitude measurement accuracy of 0.2° and superior stability, its performance surpasses that of certain professional inclination angle instruments.
By incorporating the Z-axis heading angle into the geomagnetic sensor fusion filter, this sensor efficiently resolves cumulative errors stemming from gyroscope integral drift in the 6-axis algorithm, ensuring stable output of heading angle data over extended periods.
