Claim One:
1. A method of navigating a procedure relative to an anatomy with a tracking system including a localizer and a tracking sensor positioned relative to the anatomy, comprising: providing a plurality of coils in the tracking sensor in a fixed geometry; positioning the tracking sensor at a location relative to the anatomy; determining a position of each of the plurality of coils; determining the position of at least one of the plurality of the coils based at least in part on the determined sensed position of the plurality of coils, wherein determining the position includes determining a geometry of each of the coils and comparing the determined geometry to the fixed geometry; determining a position of at least a sub-plurality of the plurality of coils including a geometry closest to the fixed geometry of the plurality of coils in the tracking sensor; and averaging the determined position for each of the plurality of coils.
