Gyro Scale Factor Errors Compensation Technology in Laser Gyro Strapdown Inertial Navigation System
摘要
Abstract
To improve the navigation precision of laser gyro strapdown inertial navigation system ( SINS ) , this paper emphasizes the factor analysis of laser gyro scale factor,and builds the exact mathematical mod-els. Scale factor of a laser gyro is correlated with its material,temperature and field length. Analysis shows that the performance of frequency stabilization and reciprocator rotation is optimal. Table simulations and sailing experiments show that this technology is convenient,and the attitude precison can be improved by a-bout 8. 7". It is meaningful for improving the measurement precison of SINS.关键词
