| Abstract: | In the paper, the rotation vector algorithm for SINS attitude updating is introduced, and the algorithm drifts of mathematical platform caused by the base coning motion are analyzed in detail as well. A new scheme for optimizing the four-sample rotation vector algorithm is proposed, which is realized by solving the contradictious equations. The comparison among one-sample, two-sample, three-sample and four-sample rotation vector algorithm drifts are made. |
