Recurrent Implementation of Integral Magnetometer Calibration Algorithm Using the Measurements of a Three-Axis Gyro

Abstract

The paper addresses the practical implementation of a calibration algorithm for a magnetometer integrated in an electronic device, using synchronous measurements of a gyroscope. Recurrent expressions have been derived for accumulating the intermediate matrices, due to which there is no need for accumulating the full set of primary measurements of vector counters. An algorithm has been formulated for determining the time point when accumulation stops and calculation of calibrated parameters starts.
