摘要
Abstract
The factors that causing the zero drift of the fiber optic gyro were analysed. The drift caused by the earth rotation and the fabrication error of the FOG was calibrated in order to meet the needs of practical application. The drift model related to temperature and rate of temperature change was built. The drift experiment of FOG was conducted under the condition of variable temperature. With the experimental data we fit the drift curve using the least square method and then predict the trend of the temperature drift using the drift model. The zero drift after compensation decreased to 15% of the drift before compensation.关键词
