Abstract
Apparatus for determining the position and orientation of an object relative to a reference frame, comprising: a generator (16), associated with the reference frame, which produces a magnetic or electric field pattern rotating about a fixed axis; a plurality of detectors, each of which generates at least one signal responsive to at least one of the electric and magnetic fields at at least one point associated with the object; and calculation circuitry, responsive to the at least one signal, which determines the coordinates of the at least one point associated with each of said detectors with respect to the generator, based on the total field strength at the at least one point, and which determines the three-dimensional position and orientation of the object, wherein the generator comprises three dipole radiators and a driver which drives the three dipole radiators with amplitudes and phases such that said magnetic or electric field pattern is generated.
