Hard iron offsets

WebApr 7, 2024 · The locus of the magnetometer readings lies on the surface of the sphere centred in zero field and the radius is equal to the magnitude of the geomagnetic field. The hard-iron interference adds fixed offset in each axis to all measurements. WebApr 1, 2024 · The quality of the hard iron offset correction estimate is judged by the R-squared metric. When the variation in the magnetic data set NOT influenced by hard iron offsets, the Mx, My and Mz correction estimates tend to zero and R-squared tends to 1.0.
