The Fraunhofer-Gesellschaft (www.fraunhofer.com) currently operates 76 institutes and research institutions throughout Germany and is the world’s leading applied research organization. Around 30 000 employees work with an annual research budget of 2.9 billion euros. 

The Fraunhofer IIS in cooperation with the TU Ilmenau have established a testbed to enable the localization of mobile endpoints using the LPWAN standard »mioty®« for application in current research topics such as the Internet of Things (IoT). The localization is based on time difference of arrival measurements (TDoA).

The testbed consists of several base stations distributed throughout the city of Ilmenau, allowing localization of mobile endpoints within this area. However, the geometric arrangement of the base stations influences the achievable accuracy. This phenomenon is called Dilution of Precision (DOP). Within this thesis, the DOP for different base station arrangements must be evaluated to obtain the best localization accuracy within different scenarios. This includes performance analysis with an increased number of base stations and heuristics to select the best-performing pairs of base stations in scenarios with multiple base stations. This selection can be based on different parameters, like the signal-to-noise ratio at different base stations.

You are interested in combining research and practices and would like to develop further in the field of localization systems?


Then have a look at our offer!

What you will do

  • You conduct literature research on the principles of TDoA localization and Dilution of Precision
  • You familiarize yourself with the existing framework
  • You describe the DOP value with different base station arrangements and different numbers of base stations
  • You develop different heuristics to select the best-performing base stations based on accuracy-determining parameters, like the signal-to-noise ratio
  • You carry out simulative verification of the investigations

What you bring to the table

  • You are currently studying electrical engineering, information technology, mathematics, or similar
  • You have experience in programming, preferably Python
  • You are interested in localization and the development of new algorithms

What you can expect

  • Flexible working hours
  • Open and friendly team work
  • Varied tasks with room for creativity
  • Exciting seminars and events
  • Networking with scientists
  • Active contribution in applied research
  • Interesting an innovative projects
  • Mentoring program »josephine®« for talented female students

Weekly working hours are determined by agreement. You can start from now on (as an intern for a period of at least three months ). You can reduce your hours before exams and increase them during semester breaks. You can flexibly determine the working days. After your studies, you have the option of working with us full or part time.

We would be happy to offer you the opportunity to write a bachelor's thesis in cooperation with us in the above-mentioned subject area. The thesis will be assigned and carried out in accordance with the rules of your university. For this reason, please discuss the thesis with a professor who can advise you over the course of the project. 

We value and promote the diversity of our employees' skills and therefore welcome all applications - regardless of age, gender, nationality, ethnic and social origin, religion, ideology, disability, sexual orientation and identity.
