An error estimate model of rotation vector was analyzed for the strapdown attitude algorithms.Based on this model ,some kinds of high_accuracy strapdown attitude algorithms were deduced.Analysis,comparison,and simulation were made with the algorithms.The result demonstrates that the proposed algorithms can significantly reduce the dynamic error and improve attitude accuracy.
