0.00016 deg/√hr Angle Random Walk (ARW) and 0.0014 deg/hr Bias Instability (BI) from a 5.2M-Q and 1-cm Precision Shell Integrating (PSI) Gyroscope
Autor: Guohong He, Jae Yoong Cho, Jong-Kwan Woo, Khalil Najafi, Sajal Singh
Publikováno v: 2020 IEEE International Symposium on Inertial Sensors and Systems (INERTIAL).
We report record-high performance from a fused-silica micro Precision Shell Integrating (PSI) gyroscope. The PSI gyroscope uses a fused-silica resonator with a diameter of 1 cm and a mechanical quality factor (Q) of 5.2 million. The gyroscope has an

$0.0062\ {}^{\circ}/\sqrt{hr}$ Angle Random Walk and $0.027\ {}^{\circ}/hr$ Bias Instability from a Micro-Shell Resonator Gyroscope with Surface Electrodes
Autor: Jong-Kwan Woo, Guohong He, Jae Yoong Cho, Khalil Najafi, Sajal Singh
Publikováno v: 2020 IEEE 33rd International Conference on Micro Electro Mechanical Systems (MEMS).
This paper reports measured results for a fused-silica precision shell integrating (PSI) micro gyroscope employing out-of-plane drive/sense transduction mechanism. The PSI gyroscope is made with a 5 mm radius shell resonator operating in $n=2$ wine-g
