SYSTEM AND METHOD FOR CONTINUOUS MONITORING OF A GYROSCOPE

Systems and methods are provided for continuously monitoring operation of a sensing device, in which the sensing device includes a MEMS gyroscope and a quadrature feedback loop coupled to the MEMS gyroscope, the quadrature feedback loop including a quadrature feedback controller. A test signal generator is configured to generate and apply a test signal to the quadrature feedback loop at an input of the quadrature feedback controller. A fault detector is coupled to an output of the quadrature feedback controller. The fault detector is configured to receive a quadrature feedback signal, detect effects of the test signal in the quadrature feedback signal, and generate a monitor output indicative of the operation of the sensing device base on the detected effects of the test signal.
