一种实用的激光陀螺寻北仪数据处理技术

An applied method of data processing based on laser gyro north-finder

本文针对车载环境下单位置激光陀螺寻北仪的输出信号进行了分析处理,设计了FIR低通数字滤波器抑制高频扰动,设计了一种利用加速度计进行陀螺误差补偿的低频扰动的抑制算法。Matlab仿真结果表明,本文的方法能够有效地抑制扰动,提高寻北仪寻北精度。

This paper analysis the output data of laser gyro north-finder which is installed in vehicle, we design FIR low-pass digital filter to restrain high frequency disturb, and design algorithm to compensate gyro low frequency disturb using accelerometer.The Matlab simulation result shows that this method can restrain disturb effectively, then it will improves the precision of the north-finder.
