Abstract
The present invention describes a method to calibrate an angular measurement device using acceleration measurement device. The angular rate measurement device includes at least one angular measurement sensor, wherein the acceleration measurement device is able to distinguish the direction and strength of gravity. By performing the calibration method the scale factor(s) of the angular measurement device and the strength and direction of gravity can be obtained and/or corrected. An embodiment according to the method of the present invention describes optional use of a communication network to perform necessary evaluation and calculation steps at a remote device.
