Measurement Techniques Aims and scope

This paper describes a mode of functioning of a wave solid-state gyroscope with a quartz resonator used as a sensing element. The components of the gyroscope errors are considered, associated with mass distribution inhomogeneity in the resonator with an axisymmetric structure, vibrations of the gyroscope base, defects in resonator excitation systems, and inaccuracies in the installation of electrodes to receive information about the resonator micromotion. Sources of these errors cause the splitting of the natural frequency of the resonator. The greatest influence on the gyroscope accuracy is exerted by an error due to inhomogeneity of the mass distribution in the resonator. To reduce this error, we propose to use compensatory impact on the gyroscope, produced in the electronic balancing unit and based on the analysis of the gyroscope output signals. An algorithm to operate this unit has been developed and studied, which enables us to increase the accuracy of gyroscope measurements.
