Hi Benjamin,
Thank you for your question.
It seems to me that your question is not directly related to ArcGIS Urban. Does the online documentation for the Tracking Server answer your question? You can find it here: Tracking Server Help
In case you do not find a satisfying answer there, I recommend to post your question in the GeoEvent space of GeoNet. This is the space where the corresponding experts hang around.
Best Regards,
Dominik
