Abstract
The fiber optic gyroscope (FOG) has become to one of the most important sensors in developing due to light in quality, high accuracy, compact in dimension and long life. These features have developed new applications of the gyroscope not only in conventional aerospace application area but also in industrial aerospace, such as control and navigations of unmanned vehicles, antenna/camera stabilizers, and so on. Fiber coil is the core of fiber optic gyroscope. The accuracy of fiber optic gyroscope depends on the temperature performance of fiber coil.

In this paper, the temperature transient error model was built based on discrete mathematics model of SHUPE error in the Fiber optic gyroscope and the element physical model of the fiber coil. Based on the temperature distribution model mentioned above, the effects of the coil with different winding method and different geometric dimensions on the temperature performance of FOG were simulated under the same temperature condition. Theoretical analysis and experimental results showed by optimizing the design of the fiber coil, the temperature error of fiber coil can be reduced obviously.
