Abstract

The architecture and performance of single axis digital closed-loop FOG are first described. To achieve high precision and large dynamic range, the optic sensor of single unit uses a multifunction integrated optic chip (MIOC), and fiber used in FOG are polarization-preserving fiber. The signal detection scheme of single axis FOG is also analyzed. Based on single axis unit, three-axis FOG scheme is presented. The optic sensor of three-axis unit includes three MIOC, and the signal detection part is optimal designed. To meet the requirement of real-time processing, high speed digital signal processor (DSP) is used as center processor. Finally, the test results of single-axis digital closed-loop FOG are presented. As the results shows, the bias drift of 0.1 (deg./h) is achieved.
