“…The authors in [15,16] use a gyroscope to align the axes of an accelerometer and a magnetometer. The authors in [17,18] exploit the fact that the measured magnetic inclination angle should be locally constant across different measurements when the accelerometer is still and the magnetometer is away of magnetic disturbances in order to align the axes of the two sensors.…”

In this work, we propose an algorithm for joint calibration and axes alignment of a 3-axis accelerometer and a 3-axis magnetometer. The proposed algorithm applies when the two sensors are fixed on the same rigid platform. It achieves accurate calibration without requiring any external piece of equipment like a turntable for the accelerometer or Gauss magnetic chamber and Maxwell coils setup for the magnetometer. The efficiency and accuracy of the proposed algorithm are evaluated using experimental data.
