载体机动对惯性导航系统精度的影响分析

Analysis on Effect of Carrier Shifting to Precision of Inertial Navigation System

根据惯性导航系统的工作原理，利用VB语言与平台惯导系统部分的数学模型COM组件，完成了惯性导航系统在动机座条件下的误差仿真，并对仿真结果进行了分析，给出了惯性导航系统误差在载体机动阶段以及机动结束后短时间内的变化趋势。分析结果表明，在载体机动过程和机动结束后短时间内，惯导系统将产生较大的误差，影响惯导系统的精度。

According to the work principle of the Inertial Navigation System（INS）,The paper accomplished the error simulation of the INS on the moving base, and then analyzing the result. According to the result, The accuracy of the INS would be affected during the time that the ship is shifting or after finishing shifting in a short time. In order to improve the accuracy of the INS, the information exported could not be used until the INS works in the steady state.
