An apparatus includes an endoscope, a navigation sensor, and an interface feature. The endoscope includes a body, a shaft extending distally from the body, and a window located at a distal portion of the shaft. The navigation sensor is position at the distal portion of the shaft. The interface feature can couple the navigation sensor with an image guidance system. The navigation sensor can cooperate with the image guidance system to provide feedback indicating a position of the navigation sensor in three-dimensional space.
