Abstract. The article deals with the problem of identifying the dynamic parameters of the resonator of a solid-state wave gyroscope, based on the signals measured when the sensor is operating in free-run mode. The search for the dynamic parameters of a solid-state wave gyroscope is one of the most important operations of the quality control of its production. The paper describes two methods for determining the physical parameters of a quartz resonator of a solid-state wave gyroscope. For each method, the mathematical substantiation of the relationship between the dynamic behavior of the resonator and its physical parameters is given. On the basis of each of the techniques, an algorithmic support for the extraction of the physical parameters of the resonator of a solid-state wave gyroscope is presented. The research of the accuracy of calculating the visual parameters by the described methods on experimental data of a resonator with known parameters has been carried out. The results obtained show the practical applicability of the described methods. An example of using the methods described in the work is the identification and control of the dynamic parameters of a quartz hemispherical resonator of a solid-state wave gyroscope at the technological stage of “balancing”.
