Research on the equivalent rotating algorithm for SINS
The strapdown inertial navigation algorithm includes the solution of the attitude matrix and extraction of the attitude angle, the solving algorithm of the attitude matrix is the core of the strapdown inertial navigation algorithm, so the attitude matrix algorithm with the high precision is important. The angle increment of gyro is used to gain the rotating vector. This method can compensate the non-swapable error. Therefore this algorithm is used in the strapdown inertial navigation system. We compare the two-sample algorithm with the three-sample algorithm in this paper. At last, we simulate the two algorithms in MATLAB and discover that the precision of the three-sample algorithm is higher than the two-sample algorithm.
