摘要：
This paper analysis the relationship between Allan variance and the MEMS gyroscope random error term, describes the method of forming the Allan variance graph, and uses a group of MEMS gyroscope data to get the allan log-log plot. Then we propose a new method of fitting a straight line, and get three different slope of the straight line, which as a basis of obtaining the three corresponding MEMS gyroscopes random error terms. After comparing with the traditional methods of a least squares fit, we establish the feasibility of this approach.
