摘要

摘要: 设计了单轴旋转式激光陀螺捷联惯导系统的对准方案, 分析了影响旋转对准精度的惯性器件误差参数,同时对不同惯性器件误差对应的对准精度进行了比对分析, 并进行了仿真试验验证。仿真结果表明, 天向陀螺标度因数非对称性误差、天向陀螺标度因数误差对航向角对准精度的影响较大, 该结论可为单轴旋转式激光陀螺捷联惯导系统的设计提供参考。

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.
