Abstract
To correct for the residual sensor errors of the laser gyro strapdown inertial measurement unit (LS1MU), the analytical algorithm based on attitude and velocity open-loop updating of the LSIMU is provided. The navigation parameter output errors of the strapdown inertial navigation system (SINS) contain certain residual sensor errors that can be evaluated by rotating and static navigation test. The analytical solution of the scale coefficients error and installation error can be deduced from the analysis of the open-loop navigation system error equations. By these, the certain residual sensor errors can be corrected. The verify experiment based on two-biax position turntable shows that only part parameters of residual sensor errors can be identified due to restrict by freedom degree. The field-test shows that the approach is feasible.关键词
