 摘要：弹载低精度陀螺仪的随机常值漂移严重影响到弹体姿态解算的精度。为了解决这一问题，提出了以装订值作为姿态基准，采用姿态匹配传递对准对弹载低精度陀螺仪的随机常值漂移进行估计的算法。对随机常值漂移为10°/h的低精度陀螺仪进行仿真，结果表明采用该算法经过40 s的估计后，随机常值漂移估计值趋于稳定且估计精度较高，从而证明该方法是行之有效的。 |

| Abstract：The random constant drift of the low accuracy gyroscope has a serious effect for attitude algorithm.In order to solve this problem,an algorithm which adopts attitude matching transfer alignment method to estimate the random constant drift of the low accuracy gyroscope is introduced.Simulation result shows that,when the gyroscope random constant drift is 10°/h,after estimating of 40 s,the estimating values trend to stabilize and higher estimation accuracy.It is proved that the method is effective. |
