Moving State Marine SINS Initial Alignment Based on High Degree CKF

Moving State Marine SINS Initial Alignment Based on High Degree CKF

A new moving state marine initial alignment method of strap-down inertial navigation system (SINS) is proposed based on high-degree cubature Kalman filter (CKF), which can capture higher order Taylor expansion terms of nonlinear alignment model than the existing third-degree CKF, unscented Kalman fi...
