A new web-based interface is now available to GNSS community thanks to the EU-funded project TestCase: the GSTI (GNSS Simulation and Testing Infrastructure) provides access to detailed information about testing tools or infrastructure, including location, technical features, conditions of use, typical use cases and points of contact. TestCase project is managed by the French company FDC and CTAE has been responsible of the design and development of the portal and the technical back-office support in the operational phase of the project.
