Satellite Navigation

The satellite navigation research team develops system concepts and is involved with the European navigation satellite system Galileo. We analyze navigation signals for freely available Galileo services (Open Service, High Accuracy Service) and for encrypted services (PRS). We also conduct studies in key areas of application, including for aviation or for securing critical infrastructure (e.g. mobile networks). Work on developments to protect Galileo signals from being faked (signatures, watermarks) is another focus in this field. 

Examples of projects:

• Signal design for Galileo 2^nd Generation
• Spoofing/interference, GNSS signal generator
• Simulation of GNSS satellites with UAVs

We are developing future navigation receivers and conduct research on sensor fusion and software radio technology. This work advances the development of navigation systems for land vehicles, aircraft and spacecraft, which are employed in autonomous driving or interplanetary flight, for example. We are also successful in the area of software radio technology and sensor fusion, where we work on sensor calibration and modelling, including for GNSS antennas, inertial measurement units (IMU) and LIDAR. The results of our research are applied in

• formation flight of satellites,
• precise smartphone positioning and
• future GNSS receivers for autonomous vehicles.

Our expertise comprises systems engineering, including the analysis and simulation of navigation methods and systems, as well as the development of prototypes with embedded programming (C++, CUDA, LabView), including the electrical and mechanical integration of hardware. The capability to carry out complex measurement campaigns, e.g. on the university’s own testing track, completes our portfolio.
