Abstract
Error sources related to aerodynamics of an inertial sensor resonator are detected by modulating the distance between the resonator and the underlying substrate and sensing modulated error signals in the accelerometer that are induced by such modulation. Compensating signals may be provided to substantially cancel errors caused by such error sources.
