Based on the reliability test technique, the feasibility of accelerated degradation test for fiber optic gyros （FOG） was studied in this paper. The performance variation of components used for FOG in long-term application condition, and the effect on the FOG were analyzed. The possibility of the performance degradation of FOG was illustrated, which was proved by experimental data of FOG for long-term application. The reliability pre-research test was utilized to study the accelerating ability of FOG performance degradation with temperature environment stress. By analyzing the performance data under temperature-accelerated stress, the accelerated ability of performance degradation was demonstrated. The accelerated degradation test for FOG is feasible.
