Zusammenfassung:	A navigation system for navigating a medical instrument is provided. The system includes a localizer, a tracking array, and a processor. The tracking array has a first tracking face and a second tracking face which are coupled to one another and collectively include a plurality of optical tracking elements. The processor is configured to measure relative positions of the plurality of optical tracking elements while visible to the localizer, measure relative positions of the at least one optical tracking element of the first tracking face and at least one optical tracking element of the second tracking face while visible to the localizer at the same time, and create a composite rigid body based on the measured relative positions of at least one optical tracking element of the first tracking face and the at least one optical tracking element of the second tracking face while visible at the same time.
