Integrated Compensation Method of Three-axis Magnetometer in Geomagnetic Navigation

A new method for distortion magnetic field compensation of a geomagnetic vector measurement system

“…Wu et al presented a constrained total least-squares calibration method for three-axis magnetometer in vehicular applications [17]. Li et al proposed an integrated compensation method to suppress the distortion field of underwater vehicles [18]. Vasconcelos et al proposed a maximum likelihood estimator (MLE) algorithm in uninhabited autonomous vehicles to compensate magnetic distortions [19].…”

Improving robustness of the MAV yaw angle estimation for low‐cost INS/GPS integration aided with tri‐axial magnetometer calibrated by rotating the ellipsoid model

“…Generally, they can be divided into two categories: dependent‐calibration with the aid of external devices or sensors [16–21] and self‐calibration based on the error model of the magnetometer [22–25]. Dependent calibrations usually utilise the reference information from external instrument such as gyroscope [16, 17, 20], 3D Helmholtz coil [18, 19], intermediate quaternion estimation by inertial fusion [21], and turntable [26]. They can achieve better performance, but the calibration process is at risk of failure when the external devices or sensors are out of order.…”

Sensor Fusion for Effective Hand Motion Detection

“…MEMS accelerometers are subject to bias error, scale factor error, misalignment errors and stochastic noise [44] [69]. Furthermore, the local magnetic fields can disturb the sensor output.…”
