Multi-Sensor Calibration of Low-Cost Magnetic, Angular Rate and Gravity Systems

Sensors, 2015
We present a new calibration procedure for low-cost nine degrees-of-freedom (9DOF) magnetic, angular rate and gravity (MARG) sensor systems, which relies on a calibration cube, a reference table and a body sensor network (BSN).

Magnetometer Calibration Using Inertial Sensors

IEEE Sensors Journal, 2016
In this work we present a practical algorithm for calibrating a magnetometer for the presence of magnetic disturbances and for magnetometer sensor errors. To allow for combining the magnetometer measurements with inertial measurements for orientation estimation, the algorithm also corrects for misalignment between the magnetometer and the inertial ...
