This paper investigates an efficient calibration method of 6 DOF acceleration sensor systems using multiple dual-axis accelerometers. So far, we have developed a calibration method to our system as sensitivities of 6 accelerometers were independent each other. But, actually, in dual-axis type accelerometers, there exist some dependency among each axis-sensitivities. Then, we reconstruct a new calibration method to above case, and investigate the influence of the error marging included in calibration. As a result, it is shown that the geometrical errors to be identified which absolute value is small or near 0 compared with other should be assumed 0 from the beginning, and we can decrease the number of calibration data and improve the efficiency of the calibration.
