  • METHOD AND SYSTEM FOR CALIBRATING AN INERTIAL SENSOR
    Publication number: 20140074418
    Abstract: A calibration system (20) configured for communication with an inertial sensor (22) includes a signal generator (24) and processing system (26). A calibration process (60) performed using the calibration system (20) includes applying (90) an electrical stimulus (44) to the inertial sensor (22), receiving an output signal (46) from the sensor (22) produced in response to the electrical stimulus (44) and determining a sensitivity (108) of the inertial sensor (22) to the electrical stimulus (44) in response to the output signal (46) and an applied voltage of the electrical stimulus (44). A sensitivity (112) of the inertial sensor (22) to an inertial stimulus is calculated using the sensitivity (108) and a measured resonant sensitivity (114) of the inertial sensor (22), and the calculated sensitivity (112) is utilized to adjust a gain value (56) for the inertial sensor (22) to calibrate the sensor (22).
