加速度计横向误差对无陀螺捷联惯导的影响

The Influence of Free From Gyros Strap-Down Inertial Accelerometer Transverse Error Navigation System

现在,国内外越来越重视对无陀螺捷联惯导系统的研究,然而在解算惯性组合基本分量时把加速度计理想化了,忽视了加速度计横向输出对解算结果的影响,从而影响了无陀螺捷联惯导系统的制导准确度。将加速度计的横向输出带入了解算过程,与传统解算过程所得的结果比较,系统基本分量更加精确,对提高无陀螺捷联惯导系统的制导准确度有重大意义。

Now, the study of Free from gyros strap-down inertial navigation system is more and more important at here and abroad, but it took aecelerometer as idealized when it computed the elementary component of inertial measurement unit, the effect of aeeelerometer transverse output on compution result is ignored so as the lead accuracy of the Free from gyros strap-down inertial navigation system is effected. To take the transverse output of the accelerometer account to compute process, compared with tradition calculation, the result is more accurate, which have important meaning to improve the lead accuracy of Free from gyros strap-down inertial navigation system.
