Calibration of Installing Errors of Laser SINS

According to the performance index of strapdown navigation system and utilizing the doubleaxis turn table with arc second position accuracy,a rotating experiment method is given to calibrate the scale errors and installing errors of the laser gyro.This paper illustrates the theory of rotating experiment methos in detail,and discusses the accuracy of the experiment.The method is believed to meet the performance requirements of laser gyro strapdown system.
