Coriolis vibrating gyroscope (CVG) with cavity resonators are promising inertial angle and angular velocity sensors. Cavity resonators are sensitive elements of the CVG; they can be produced of quartz glass or metal. CVG with a metal resonator demonstrates high vibration resistance and vibration strength compared to a CVG with a quartz resonator. Therefore, a CVG with a metal resonator is more suitable for dynamic land, sea, and aerospace-based carriers. For these carriers based on a CVG with a metal resonator, measuring modules for orientation, stabilization and navigation systems of middle class accuracy can be made, comparable to similar systems using some types of fiber-optic and rotor vibration gyros. Preparing the production of a CVG with a metal resonator required solving the following tasks: developing control electronics, tuning and calibrating techniques for the given ranges of measuring the angular velocities of carriers in a wide temperature range, choosing a resonator material and working out the technological cycle of its manufacture taking into account mechanical and heat treatment. A series of research and development practices has been completed for the development of the resonator balancing technique that eliminates four forms of mass defect distribution. In the series production a CVG with a metal resonator having technical and operational characteristics that meet the technical conditions for its manufacturing was obtained. The dynamics features of a Coriolis vibrating gyroscope (CVG) with a metal resonator and the technology of its production have been considered. The technical characteristics of a CVG, manufactured by Michurinsky “Progress” plant, are given.
