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,以及双回路的二子样、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。
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 fore - 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.
