Development of a vibrational error model of a hemispherical resonator gyroscope
2018 25th Saint Petersburg International Conference on Integrated Navigation Systems (ICINS), 2018 A mathematical model of vibration error for a hemispherical resonator gyroscope is considered. The expression for the resonator standing wave precession coefficient under the conditions of base vibration is obtained.

Effect of diaphragm perforation on quality factor of hemispherical resonator gyroscope
2015 Transducers - 2015 18th International Conference on Solid-State Sensors, Actuators and Microsystems (TRANSDUCERS), 2015 In this work, thermoelastic damping (TED) effect of diaphragm perforation on a hemispherical resonator is investigated, and is experimentally shown to improve the quality factor of the resonator. Specifically, this paper reports the quality factor improvement of a very high Q hemispherical resonator gyroscope (HRG) through making a hole on the ...

On bifurcation in dynamics of hemispherical resonator gyroscope
AIP Conference Proceedings, 2018 A mathematical model of wave solid-state gyro (HRG) are constructed. Wave pattern of resonant oscillations was studied applying normal form method. We calculate the Birkhoff-Gustavson normal form of unterturbed system.

The operation and mechanization of the hemispherical resonator gyroscope
2018 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2018 The Hemispherical Resonator Gyro (HRG) is unique in the area of high accuracy inertial sensors. One of its very first selected applications was on the Cassini mission to Saturn, its Rings, and Moons. Since that time it has been the chosen gyro technology for precision space missions both military and commercial.
