摘要：
A method of obtaining information about the position and/or orientation of a magnetic component relatively to a magnetometric detector, the magnetic component and the magnetometric detector being moveable independently from each other relatively to a static secondary magnetic field, the method comprising the steps of: measuring in the presence of the combination of both the magnetic field of the magnetic component and the static secondary magnetic field essentially simultaneously the strength and/or orientation of a magnetic field at at least a first position and a second position spatially associated with the magnetometric detector, the second position being distanced from the first position； and combining the results of the measurements to computationally eliminate the effect of the secondary magnetic field and derive the information about the position and/or orientation of the magnetic component.
