Calibration of Misalignment Angles of Laser Gyro Triad

摘要

Misalignment angles of gyro triad will result in additional gyro drift. Thus, the precision of inertial navigation system is reduced. To meet the calibration requirements of misalignment angles of laser gyro triad,based on profound analysis of the installing error model,a rotating experiment method is proposed to calibrate the misalignment angles of laser gyro triad,and then measures are proposed that calibration effect can be improved based on analysis of factors that calibration error is caused. Thus, the requirements for the calibration of installing error can be meet.
