摘要: 文章推导了三子样二次迭代捷联惯导姿态更新算法,提出了以锥误差最小为优化标准的三子样二次迭代优化算法,并对单回路的三子样、四子样,以及双同路的二子样、三子样的算法漂移进行了对比计算,发现三子样二次迭代优化算法优于其余三种算法.

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.
