Philipp Zingerle is a PhD student and university assistant at the Institute of Astronomical and Physical Geodesy at the Technical University of Munich. His main research focuses on the improvement of quality and resolution of global gravity field models by exploiting new possibilities facilitated through modern supercomputing systems (such as SuperMUC-NG, hosted by the Leibniz Supercomputing Centre). One of the main challenges in this field is the optimal combination of lower-resolution, high-accuracy satellite gravity field information with higher-resolution, varying-quality terrestrial observations. Within the study an adapted least-squares adjustment approach is pursued which accomplishes to resolve this problem in a mathematically optimal way while keeping the computational effort within feasible limits. As a first result of his work, the new XGM2019e model has been published recently, which makes use of this method as well as further improvements.
