| Abstract: | The three-sample-and-two-time iteration algorithm for sinS attitude updating was derived,and the optional three-sample-and-two-time iteration algorithm for sinS attitude updating was proposed.The comparison among three-sample and four-sample rotation vector algorithm drifts of single loop and two-sample and three-sample algorithm drifts of double loop was made.It can be found that the optional three-samples and two time iteration algorithm is better than the other three algorithms. |
