This widget is deprecated. The features (1) connection to NDI tracking devices and (2) handling of navigation tools are available in the pluging org.mitk.gui.qt.igttracking in a current version. The new concept to access the tracking devices is to use microservices. This can be achieved very simple by using the QmitkNavigationDataSourceSelectionWidget. You can find an example in the IGT tutorial step 2 / org.mitk.gui.qt.igtexamples (view TrackingLab).
