This invention discloses a system for tracking one or more objects (22) within a region of interest, including at least one electromagnetic field generator (20), fixed with respect to an external frame of reference, at least one passive transponder (30), fixed to an object (22) being tracked, wherein an electromagnetic field generated by the electromagnetic field generator (20) causes the transponder (30) to generate electromagnetic signals and at least one electromagnetic sensor (24), fixed with respect to the external frame of reference, which receives electromagnetic signals generated by the transponder (30) and determines the three-dimensional position and three-axis rotational orientation of the object (20) using these signals. A method of tracking translation and rotation of one or more objects within a region of interest is also disclosed.
