摘要

The device has an element connected with a base element (10) to-tracked. A set of reflection elements (18) is connected with the base element, where the reflection elements are arranged with a spatial spacing from each other to simultaneously perform a position determination and orientation determination of the to-be tracked element. The base element comprises a clasp element (12) for wedging fastening with the to-be tracked element. The reflection elements are connected with the base element over a rod-shaped intermediate element (16).
