| 摘 要： | 介绍了光纤陀螺在车载导航系统中的应用，指出漂移是存在于光纤陀螺系统中使得输出信号产生较大偏置误差的一种因素，为提高车载导航系统的测量精度，提出采用小波分析对输出信号进行滤波处理的方法，通过仿真结果验证了该方法的有效性。

| Abstract: | The application of the optical fiber top was introduced in the vehicle carrying guidance system, and pointed out that the drifting was a kind of factors to cause the bias error of output signal in the optical fiber gyrosystem, the filter processing for the output signal was proposed by using the wavelet analysis method, to enhance the measuring accuracy of the vehicle carrying the guidance system and to confirm the method validity through the simulation result. |
