Abstract

A tracking device for a navigation system that includes a localizer. The tracking device has a tracking body. At least one tracking element is supported by the tracking body and configured to transmit a tracking signal for the localizer. A visual indicator is supported by the tracking body and has an emitter configured to generate a visible light. A tracker controller supported by the tracking body is configured to receive a signal from the navigation system indicative of the tracking signal being received by the localizer, and in response, control the visual indicator to activate the emitter to generate the visible light to produce a color to indicate to a user that the tracking signal is being received by the localizer.
