BPN603: Micro Rate-Integrating Gyroscope

Project ID BPN603
Website
Start Date Tue 2011-Feb-01 13:58:36

Abstract The goal of this project is to realize a micro rate-integrating gyroscope that produces an output signal proportional to rotation angle rather than rotation rate. If successful, this device would eliminate the need of integrating the gyroscope's rate output to obtain the angle. Realizing a micro rate-integrating gyroscope can be achieved by fabricating hemispherical resonating shells with extremely close frequency matching (delta f < 10 Hz) and a very high quality factor (Q > 1 million). Structures must be highly axisymmetric and micro-finished to nanometer scale roughness.
