We report a novel Cs-Xe-129 atomic spin gyroscope (ASG) with closed-loop Faraday modulation method. This ASG requires approximately 30 min to start-up and 110 degrees C to operate. A closed-loop Faraday modulation method for measurement of the optical rotation was used in this ASG. This method uses an additional Faraday modulator to suppress the laser intensity fluctuation and Faraday modulator thermal induced fluctuation. We theoretically and experimentally validate this method in the Cs-Xe-129 ASG and achieved a bias stability of approximately 3.25 degrees /h. (C) 2013 AIP Publishing LLC.
