摘要
惯性导航平台存在航向效应,对自对准精度影响较大。研究探讨存在航向效应的导航平台的快速自对准技术。首先根据巡航导弹作战要求,选用两位置、零力矩解析自对准方案,并讨论了通过优选位置转换角度保证自对准精度的方法。然后给出了利用冗余敏感轴输出信息消除航向效应影响的原因和方法。最后估算了自对准精度和对准时间。结果表明:该方案可在较短时间内以较高的精度满足巡航导弹对准精度的要求。
The auto-aligning accuracy is greatly influenced by heading-effect of the inertial navigating pl, form. The aim of this paper is to achieve a rapid auto-aligning method to solve this problem. Firstly, according to the operational requirements of the cruise missile, the two-position-zero-moment-auto-aligning method is adopted, and the transforming angle is optimized to assure the aligning accuracy. Secondly, the reason and the method to cancel the impact of the heading-effect by the output of the redundant sensor are provided. Lastly, the auto-aligning accuracy and time is estimated. It shows that this auto-aligning method can satisfy the demands of cruise missile with short time and relatively high accuracy.
