摘要

为减小光纤陀螺(FOG)启动过程中的零偏漂移

提高测量精度

提出一种基于统计产品与服务解决方案(SPSS)的光纤陀螺启动漂移补偿方法。采用SPSS计算机统计分析软件进行室温下某型惯导光纤陀螺启动漂移建模

分析发现影响光纤陀螺启动漂移的主要因素依次为温度变化率、温度、温度二次方

综合考虑后选取温度变化率作为自变量

建立启动漂移线性补偿模型。经实验验证

补偿模型有效

提高了光纤陀螺测量精度。实际应用于惯导对准

光纤陀螺启动漂移补偿后惯导航向角对准精度平均提高约70%。

Abstract

In order to reduce bias drift in startup phase of fiber-optic gyroscope（ FOG） and improve measurement precision

a compensation method for FOG startup drift based on statistical product and service solutions（ SPSS） is proposed. The SPSS statistical analysis software is applied to modeling of FOG startup drift at room temperature. It is founded that the main factors affecting FOG start-up drift are temperature change rate

temperature and temperature square. The temperature change rate is selected as the independent variable after considering many factors. A linear compensation model for startup drift is established. By the test

the compensation model is effective and can improve the FOG measurement accuracy. The alignment test results show that the accuracy of course angle is improved by about 70 % on average after compensation.
