Attitude Estimation of SINS on Dynamic Base With Decoupling Gravity Vector

Accurate and fast estimation of attitude is an important performance criteria for Strapdown Inertial Navigation System (SINS). Although many algorithms for SINS attitude estimation have been proposed by related researchers, most of them take the gravity vector as a known quantity. However, the gravity vector is inaccurate or even unknown in many cases, we have to use normal gravity instead of true...
