WebAn Extended Kalman Filter (EKF) algorithm has been developed that uses rate gyroscopes, accelerometer, compass, GPS, airspeed and barometric pressure measurements to estimate the position, velocity and angular orientation of the flight vehicle. This algorithm is implemented in the AP_NavEKF2 and AP_NavEKF3 libraries and is based on initial work ... WebMay 7, 2024 · “EKF2 Yaw inconsistent by XX deg” means that the two EKF cores are reporting different headings which is quite bad and we should try and resolve this. It seems like from the analysis above that some IMUs are suffering from high z-axis gyro drift.
