ABSTRACT:
Apparatus for determining the position of a probe in a sensing volume includes a plurality of magnetic field generating sources for generating different magnetic fields in the sensing volume, where the sources have a planar configuration and are positioned so that they at least partially overlap one another in horizontal extent and so that the sensing volume extends outwardly from the sources. The probe is provided with sensors which detect magnetic field components of fields generated by the sources. The position of the probe can be determined from the detected magnetic components. Methods for determining the probe position are also included.
