Paper Abstract

In view of the demand of space application field for long-life and highly reliable fiber optic gyroscopes, a life evaluation method for fog in space is presented in this paper. The effect of various physical fields on the performance of fiber optic gyroscope is analyzed in this paper. The temperature field and irradiation are the main environmental factors affecting the operating life of fiber optic gyroscope on orbit. The acceleration test method of temperature field and irradiated double stress double temperature point is carried out, and the performance of fiber optic gyroscope under the action of multi physical field is built. An accelerated life test evaluation method for fog is put forward. The life assessment method of fog in space can provide technical support for the design, selection and verification of the long life fiber optic gyroscope.
