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。 Based on the existing hardware, it is recognized by scholars at home and abroad to improve the alignment and navigation accuracy of the laser gyro SINS through software algorithms such as filtering. In order to evaluate the effect of laser gyroscope before and after filtering accurately and quantitatively, the Allan variance analysis algorithm is designed and the software of alignment-navigation and precision analysis and evaluation is developed. The software is researched respectively from component level and system level, Laser gyro SINS equipment to its experimental verification.
