N2 - Fiber optical gyroscope (FOG) is a kind of angle velocity sensor developed in recent 30 years, with characteristics of small volume, solid structure, fast startup and so on. FOG is an important component for high-precision navigation and control of autonomous robots. Shupe error, a kind of bias error in FOG over temperature varying environments, still exists even with strict quadrupolar winding pattern, and it affects the environment adaptability of FOG and limits the navigation performance of autonomous robots, especially in harsh environment. A novel configuration to realize optical compensation for Shupe error in FOG is promoted in our earlier paper, employing the opposite polarity of Shupe error in two FOGs respectively working with polarization maintained (PM) fiber's fast and slow axis in a single PM fiber coil. We have given a thorough theoretical analysis of this novel FOG in the earlier paper. In this paper, we mainly focus on the experimental verification of the FOG, including its closing-loop operation, static performance, basic principle of compensation of Shupe error, and choose of the coupling angles between fiber coil and integrated optic chip to make PNR error minimum. The experiment results agree well with the theoretical analysis, and the feasibility of the novel FOG is proved.
