Advances in Relativistic Positioning Systems.
The Advanced Concepts Team of the European Space Agency organizes a mini-workshop on its latest research in Fundamental Physics with particular emphasis on relativistic positioning systems. |

In this workshop we will present the results of the Ariadna project "Mapping the spacetime metric with a global navigation satellite system", a study performed by the University of Ljubljana in collaboration with the Advanced Concepts Team of ESA. This project led to the proposal of a PECS project: "Relativistic global navigation systems". The Ariadna project led to the definition of an autonomous, highly accurate and stable primary reference frame for GNSS. To that purpose we developed new theoretical tools and numerical algorithms that are readily available in the final report and on our website. The new scheme for positioning takes place in a fully relativistic framework and could be used for many areas of science such as geology or relativistic gravimetry. While the core research questions are addressed in the Ariadna study, these also led to further, more detailed issues still to be resolved such as the description of the GNSS by including all gravitational perturbations, the question on the new GNSS frame will contribute to ameliorate terrestrial frames and whether we use it for high precision experiments in space or solar system navigation.
