Error Calibration of Cross Magnetic Gradient Tensor System with Total Least-Squares Method

The magnetic gradient tensor system configured by fluxgate magnetometers is subjected to different scale factors, three-axis nonorthogonality, bias, and misalignment errors. All those errors above will influence the measurement precision directly, so the magnetic gradient tensor system must be calib...
