An apparatus and method is presented for calibrating an output(s) of an inertial measurement unit (IMU) using rotational rate as a reference. Calibrating the IMU output(s) is performed by comparing the IMU output(s) to expected output(s), where the expected output(s) are determined based on the known rate of rotation of the IMU and the centripetal force acting on the IMU due to known rate of rotation. By analyzing the differences between the expected IMU output(s) and the IMU output(s), it is possible to determine a correction factor that, when applied to the IMU output(s), calibrates the IMU output(s) by correcting for measurement errors. |
