Abstract: We report record results from a small fused-silica precision shell integrating (PSI) gyroscope. The 1-cm diameter metal-coated shell has a Q of 5.2M and provides a measured angle random walk of 0.00016 deg/√hr and in-run bias instability of 0.0014 deg/hr without any temperature compensation. This performance for such a small shell gyroscope compares well with, and is even better than, the larger mHRG and HRG devices reported previously (Table 1). This performance, in a device this small, is achieved by optimizing the fabrication of the shell resonator so it provides high Q, large mass, high frequency resonance, and low as fabricated frequency mismatch.
