摘要
Abstract
The random drift of fiber optic gyroscope (FOG) is the main error source of the strapdown inertia] navigation sys-tem (SINS). The random error of FOG should be modeled accurately to reduce FOG's random error and improve its precision. According to the theory of the time series analysis, FOG's random error model was build with autoregression AR model method. Based on this model, FOG's random error was filtered with Kalman filtering algorithm. The filtering and Allan variance analysis results proved that the FOG's random error after filtering was obviously reduced and the FOG precision was improved effectively.关键词
