The state and prospects of the development of vibration gyroscopy in Ukraine and in the world

Abstract

The work analyzes the development and current state of vibration gyroscopes in Ukraine and in the world. The development of quartz and metallic resonators of various diameters for vibrating gyroscopes is presented and analyzed. In addition, for comparison with world practice, the developments of quartz and metallic resonators of advanced foreign companies, leaders in this field, are given. The block diagrams of the standing wave control system of the vibrating gyroscope in three modes of operation: as the angle rate sensor, as the rate-integrating or whole angle mode sensor and the differential mode are considered. In the perspective, the possibility of combining all three modes in one gyroscope with automatic switching from one mode to another one is shown, for maximum use of the advantages of each mode in dependence of environmental conditions and motion parameters. The test results of gyroscope with a metallic resonator made in Ukraine, on the effect of a wide range of external disturbances are presented. The development prospects of vibrating gyroscopes and systems based on them are evaluated. The paper draws conclusions about the state and prospects for the development of vibrating gyroscopy in Ukraine.
