Matrix sensitivity calibration of 3-axis accelerometer


Matrix sensitivity calibration has been proposed to evaluate sensitivities of inertial sensors as vector values. In order to apply this method to MEMS accelerometers, the technique to measure multiple sensors at once is required. We evaluated the effects of rotational motion of a shaker and angular alignment error of sensors.
