“…The proposed method for evaluating the quality factor for self-generation loop of xenon isotope 131 and quality factor for self-generation loop of xenon isotope 129 based on the operation of AGC, which is already part of the nuclear gyro. AGC's principle of operation is based on maintaining the selected signal level by it's coefficient [10]. Given its presence, equation 2 for both self-generation loop takes the following form: In 3 A stdAGC131/129 is a given and, accordingly, known value, A stat is also known with sufficient accuracy.…”

The article presents numerical requirements for vapor cells for a nuclear magnetic gyroscope. The design requirements for the cells, such as shape, size and transparency, as well as their influence on the characteristics of the gyroscope, in particular, on the angle random walk, are considered. The process of manufacturing vapor cells and control of their parameters is described.

To adjust the stabilization systems that ensure the operation of the angular position or rate sensor based on the effect of nuclear magnetic resonance, it is required to choose the criteria for the quality assessing of sensor’s operation. The article presents the criteria of the quality of the angular sensor operating as a self-oscillation system. It is shown that the accuracy of the angular sensor increases when the proposed criteria are met.
