Integrated Compensation and Rotation Alignment for Three-Axis Magnetic Sensors Array

The differential magnetic gradient tensor system is usually constructed from the three-axis magnetic sensor array, thus making the misalignment error between the sensors become the main source of the measurement error. In addition, the sensor axial biases, scale factors, non-orthogonality, and exter...
