| 摘 要： | 为提高战车捷联惯导系统的初始对准精度,研究了二位置转动修正加速度计零偏的方法。通过对捷联惯导系统静基座的误差方程作Lyapunov变换,得到转动过程中加速度计零偏误差的传播方程,利用等效转动矢量的方法推导出方程的解析解,分析解的稳定性得出二位置对准的最优转动角度。

| Abstract: | To improve the stationary alignment accuracy of strap-down inertial navigation system (SDINS), a method of correcting accelerometer biases by two position rotation was provided. The SDINS error model was transformed by Lyapunov transformation. To solve the propagation equation of accelerometer biases in rotation, the equivalence rotation vector was used. The optimal rotation angle was derived form the stability of solutions. |
