环形激光陀螺仪随机误差的Allan方差分析

Random Error Analysis of Ring Laser Gyro Using Allan Variance Method

应用 Allan 方差法分析了环形激光陀螺仪(RLG)惯性测量组合(IMU)中激光陀螺仪静态输出信号中各种随机误差大小及其误差源。为进一步提高 RLG 的性能提供了理论依据。

The Allan variance method is used in analyzing the static output signal of the Ring Laser Gyro(RLG) in iner- tial Measurement Unit(IMU).It can determine the character of RLG and identify the source of random error.The con- clusion afford the theory for improving the character of RLG.
