Studying the atomic gyroscope magnetic shield residual magnetization by comparing parametric resonance signals

The paper presents an algorithm for measuring the residual magnetic field in the magnetic shield of a quantum rotation sensor, which is based on the analysis of cesium parametric resonance signal. The effect of the residual magnetic field in the magnetic shield of the passive shielding system of an atomic gyroscope on its performance is investigated. The form of cesium parametric resonance is analysed. The results of experimental verification of the algorithm are presented to confirm its effectiveness.
