Highest bias stability fiber-optic gyroscope SRS-5000

The aim of the current work was to produce the highest bias stability fiber-optic gyroscope SRS-5000 and to evaluate its main technical characteristics. Five prototype SRS-5000 devices were comprehensively measured and evaluated. Measured devices' parameters (ARW around 69 M°/√hour with bias stability better than 8×10
^-5
°/hour) allow to assess this type of devices as the highest-precision strategic grade fiber-optic gyroscopes, commercially available.
