Abstract
In a correction system for a magnetic field probe, the probe is first moved in a circle for calibration such that respective maximum and minimum values of a measured magnetic field vector or a respective component thereof is determined. By means of a sum formation and halving of the respective maximum and minimum value, a respective additive correction value is derived which is added to the respective measured values during navigation with the magnetic field probe. By so doing, a noise vector superimposed on the external magnetic field is eliminated.
