Robust adaptive Kalman filter for strapdown inertial navigation system dynamic alignment
IET Radar, Sonar &Navigation, Volume 15, Issue 12, Page 1583-1593, December 2021., 2021 Abstract The measurement noise covariance R plays a vital role in the Kalman filter (KF) algorithm. Traditionally, a constant R is obtained by experience or experiments. However, the KF cannot achieve optimal estimation using constant R under non‐Gaussian conditions.
