Abstract

Abstract

An alignment scheme for single-axis rotation ring laser gyroscope(RLG) strapdown inertial navigation system (SINS)is designed, and the error parameters of the inertial device affecting the alignment accuracy are analyzed. The ali- gnment scheme is validated by simulation, and the different errors of inertial devices corresponding to the alignment ac- curacy are compared. Simulation result indicates that the scale factor asymmetry error and the scale factor error of the vertical axis gyro exert significant effects on the alignment accuracy of course angle. This study may offer a reference for design of single-axis rotation RLG SINS.
