激光陀螺滤波评估方法研究

在现有硬件的基础上,通过滤波等软件算法来提高激光陀螺捷联惯导系统对准和导航精度是目前国内外学者所公认的。为了对激光陀螺滤波前后的效果进行准确、定量的评估,设计了Allan方差分析算法,开发了对准-导航及精度分析评估软件,分别从元件级、系统级对其展开了研究,并结合具体激光陀螺捷联惯导设备对其进行了实验验证。

Investigation on the evaluating method for the filtering of ring laser gyroscope

It is recognized that soft arithmetic such as filtering etc can improve the alignment and navigation precision of the ring laser gyroscope strapdown inertial navigation system(SINS)on the current hardware foundation.In order to evaluate the filtering effect of the ring laser gyroscope(RLG),the Allan variance analysis algorithm is designed,and the alignment and navigation software and precision analysis software are exploited,with which the research is developed from the view of element and system respectively.And the validate experiment is had with the RLG SINS.
