Nonlinear Frequency Modulated Gyroscope

A nonlinear frequency modulated gyroscope includes a degenerate-mode mechanical resonator, positive feedback circuits, a temperature control component, and a gyroscope controller. The degenerate-mode mechanical resonator with two or more modes are coupled via a Coriolis effect. The positive feedback circuits for each mode of the degenerate-mode mechanical resonator include an analog or digital automatic gain control that maintains oscillations of each mode at a constant amplitude. The temperature control component includes a sensor and heating elements. The gyroscope controller is an application-specific integrated circuit, a field programmable gate array, or microcontroller. The degenerate-mode mechanical resonator, the positive feedback circuits, and the temperature control component are subsystems of the nonlinear frequency modulated gyroscope.
