| Abstract: | In view of the integration of special Switch Mode Power Supply(SMPS)for fiber optic gyroscope(FOG), the influence of noise due to the variations of Pulse Width Modulate(PWM)waveform and the switch frequency on the precision of FOG is analyzed in this paper. It is proved by test that the noise of SMPS does not influence the precision of the medium grade FOG whose bias repeatability is 0.3 ( )/h. |

| Keywords: | fiber optic gyroscope accuracy pulse width modulate switch-mode power supply noise |
