The atom spin gyroscope based on quantum precision measurement has the advantages of high accuracy, small size and low cost, which is considered to be the future development direction of the gyroscope. The core component of atomic spin gyroscope is the alkali vapor cell carrying the atom spin. The stability of the alkali vapor cells heating temperature is one of the important factors to determine the accuracy and sensitivity of atomic spin gyroscope. Meanwhile, the ultra-high sensitivity of the atomic spin gyroscope makes it extremely sensitive to magnetic field noise, so it should avoid introducing additional magnetic field interference by the electronic heater. For the above requirements, the non-magnetic heating system with high stability of temperature control and low interference magnetic is designed and optimized. A non-magnetic electric heating system consisting of temperature sensor Pt1000, film heater, SMU, DAQ card, sine wave generating circuit, driving circuit and the LabVIEW software platform, is established. The test results show that the equivalent interference magnetic field is within 15 fT/Hz1/2, the short-term stability of the alkali vapor cells temperature is ±5 mK, and the long-term stability is ±10mK, which provides reliability for the performance promotion of atomic spin gyroscope.
