子平台惯导系统在动基座上传递对准的研究

Research into Tranfer Alignment of a Slave Platform Inertial Navigation System on the Moving Base

以舰载导弹中的平台惯导系统为子平台惯导系统，论述了在子平台经粗对准后，精确估算其姿态误差角、目标方位误差角、漂移率的方法对速度传递和姿态角度差传递的两种估算方法进行了理论推导和仿真计算讨论结果表明，姿态角度差传递估算法不但可解决多个未知量的求解问题。

We take platform inertial navigation system of the shipbased missile as a slave platform inertial navigation system.The precise estimation methods of the attitude error,shift rate of a slave platform and azimuth error of the target after inelegant alignment process of slave platform are discussed in this paper.The two estimation methods,velocity transfer and attitude angle difference transfer are reckoned theoretically and simulated on computer.The results show that the latter method not only can solve the multivariable problem ,but also can automatically eliminate the effect of error of attitude sensors to the estimation.That is the new idea of this paper.
