Mini-Workshop: Advances on 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 will be presented 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 there were 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.

Badges will have to be prepared by the ESTEC security at the entrance gate. In order to speed up the process, we recommend bringing with you a copy of your passport or ID card on your arrival.
How to get to ESA/ESTEC
ESTEC is located at the southern tip of Noordwijk. A map is available here.
From Den Haag (The Hague): take the A4 (direction Amsterdam) and exit at "Leiden". Follow the N206 towards Katwijk and Haarlem. Take the exit "Katwijk Noord". From there follow signs to "ESTEC" (small white squares).
From Amsterdam: take the A4 (direction Den Haag-Rotterdam) then at the junction follow the A44. Take the exit "Noordwijk-Voorhout", continue to Noordwijk and from there, follow signs to "ESTEC".
From Leiden Centraal station, take the number 33 bus to Katwijk. The bus stops in front of the ESTEC entrance gate. Please note that this bus leaves twice an hour during peak periods and only once an hour during normal hours. Journey time is approx. 30 minutes.
From Schiphol airport, either take a taxi to ESTEC (30 min), or a train to Leiden (15 min) and then the number 32 bus (see train directions above) (30 min.). By rental car, follow the "By car" instructions as above from Amsterdam.
