Physical Geodesy and Satellite Geodesy

High-precision localization and estimation of vehicle dynamics is essential for automated driving and a core competence of the Physical and Satellite Geodesy lab, TU Darmstadt (PSGD).

We are researching and developing multi-sensor fusion algorithms with focus on Global Navigation Satellite Systems (GNSS) and Inertial Measurement Units (IMU). Additionally, other sensors like wheel sensors are used for automotive applications in research projects like UNICARagil. These algorithms estimate all required states for the control of automated vehicles, meaning the pose (position and orientation), its first derivative and the acceleration as well as additional quantities e.g. the side slip angle. Furthermore, the sensor fusion algorithm also provides accuracy and integrity information.

Beside this specific topic PSGD is active in a number of research areas like geodetic reference systems, high-precision GNSS positioning in various modes, structural monitoring, satellite geodesy, physical geodesy and geodetic Earth observation in general.
