Signal Detection and Control of Hemispherical Resonator Gyroscopes [PDF]

open access: yesJournal of Sensor Science and Technology, 2012
In this paper, signal detection and control circuits for hemispherical resonator gyroscope(HRG) are designed, simulated and tested. HRG is one of the coriolis vibratory gyroscope(CVG) which has very stable quartz hemispherical resonator and shows very precise performance. HRG signals are usually modulated at the several kHz of resonant frequency.

Coupled Field Analysis of Hemispherical Resonator Gyroscope

open access: yesInternational Journal of Vehicle Structures and Systems, 2022
This work deals with the electromechanical analysis of the Hemispherical Resonator Gyroscope (HRG). The HRG is a type of Coriolis vibratory gyroscope (CVG), which uses Coriolis force to measure the input angular rate. For any CVG drive and sense mode, frequencies play a critical role, which decides the sensitivity and bandwidth of a sensor.
