Embodiment Construction
[0030] The non-magnetic heating technology of the atomic gas chamber is the key technology in the SERF gyroscope to ensure the normal operation of the gyroscope. The existing non-magnetic heating technology realizes the PID heating control of the atomic gas chamber by setting a non-magnetic heating chip and a temperature feedback element (such as Pt100). However, the driving current applied when the temperature feedback element is working will still introduce a weak magnetic field and interfere with the output signal of the SERF gyroscope. Moreover, the temperature feedback element placed on the gas chamber heating body can only measure the temperature at a point, which cannot eliminate the temperature gradient existing in the heating process of the atomic gas chamber, which restricts the further improvement of the SERF gyroscope's zero bias stability and other performance. In response to this problem, the present invention proposes a non-magnetic heating and temperature measu...
