Abstract：The temperature drift error of the FOG is one of the important factors that restrict its accuracy. In order to further es?tablish the temperature compensation model of the FOG. First,temperature experiment is designed to obtain the relationship be?tween drift and temperature in the whole temperature range. Then analyzing the temperature characteristics,the temperature error model is divided into the temperature-rise model and the temperature-fall model respectively. The temperature rising phase is divid?ed into two stages according to the temperature value,which simplifies the form of the model and improves the accuracy of the mod?el. The mode is verified by FOG measured drift data,the experimental results show that the model can effectively compensate the temperature error of the FOG. The mean and variance of the error after compensation are reduced by two orders of magnitude.
