| 摘 要： | 针对传递对准过程中基准信息时间延迟对传递对准精度的影响,给出了一种基于角速率积分最小方差曲线拟合的时间延迟估计方法.首先,记录一段时间内主、子惯导陀螺传感器的输出数据,并对该数据进行积分.然后,定义基准信息可能存在的时间延迟的最大范围,并在该范围内对主惯导数据进行逐点移位,计算曲线各对应点的差的平方并求和.最后,通过最...

| Abstract: | To reduce the error in transfer alignment caused by reference information delay,a time delay estimation method is developed based on least-squares curve fitting of the angular rate integration.First,the gyro sensor measurements of the main strapdown inertial navigation system(M-SINS) and the slave strapdown inertial navigation system(S-SINS) are recorded for a few seconds and the integration of the data is calculated.Then,the possible maximum range of the delay value is defined and the points of the curve a... |
