Small Business Innovation Research Program (SBIR) Phase II

Precision Auto Calibrated Shell Resonator Gyroscope

Micro-Electromechanical Gyroscope for Improved Inertial Navigation Systems Performance

Our goal for this Navy SBIR project is to develop a TRL-7 prototype of the BRG with excellent long-term bias stability and shock and vibration insensitivity that can operate in a military temperature range (-50 80 C) and optionally can operate at very high temperature (200 C) (i.e. bias drift < 0.01 deg/hr, angle random walk < 0.005 deg/sqrt(hr), and scale factor stability < 100 ppm). We will investigate and overcome the factors that affect the bias stability and temperature sensitivities of bias and scale factor that currently limit the performance of the Gen-1 readout-and-control electronics. We also propose to evaluate and enhance the performance of electronic self-calibration and compensation algorithms with BRG-10 prototype that will be ready TA2. We plan to test the bias stability and scale factor stability of the BRG-10 prototypes including the self-calibration and compensation algorithms in the military temperature range (-50-85 C). In TA2, we plan to continue the fabrication of BRG-10 prototypes including a dual-layer vacuum package. We plan to demonstrate excellent Q (>4 million) and ?f (<1 Hz), which are essentially needed for building a navigation-grade gyroscope.

The goal of phase II is to continue the R&D efforts initiated in Phase I. Funding is based on the results achieved in Phase I and the scientific and technical merit and commercial potential of the project proposed in Phase II.
