Testing and Analysis for Stochastic Error of MEMS Gyroscopes

Tao Zhu

Abstract

In order to reduce errors in MEMS gyroscopes to improve its performance,the stochastic error of the MEMS gyroscopes is analyzed by the Allan variance method.The paper introduced the Allan variance,analyzed the characteristic of noise observed in the MEMS gyroscope,calculated parameters of different errors and made compare with the value given in the user manual and made estimation for each gyroscope.
