FIELD: physics; measurement.
SUBSTANCE: present invention pertains to navigation technology, and specifically to a miniature gyroscopic device for monitoring orientation of wells in the oil industry as well as other industries. The gyroscopic unit comprises an evacuated case with three solid-state wave gyroscopes inside it. The case is a single-section rod type monolithic structure. Each of the solid-state wave gyroscopes is made of two parts, tightly glued to each other, or soldered to a hemispherical resonator. Inside the resonator there are quartz glass plates with metallised electrodes for generating and recording oscillations. The un-evacuated part of the case can optionally be made with three more spare cavities for holding accelerometers of the navigation system.
EFFECT: improvement of technical operation qualities, reduced costs and cutting on time spent on making such a device.
