Quality Factor Improvement Method of Honeycomb-Like Disk Resonator Gyroscope

This paper reports a method to improve the quality factor of the honeycomb-like disk resonator gyroscope (HDRG). Based on this method, a novel HDRG prototype is designed, fabricated and tested. The new-designed HDRG has a more than 4-fold increase of tested quality factor compared with the former design, resulting in about 3 times improvement of angular random walk and 30 times improvement of bias-instability.
