Abstract:	At the end of 2024, the ‘Resilient GNSS Challenge’ was organized by the European Space Agency (ESA) and hosted during the 11th ESA Workshop on Satellite Navigation Technologies (NAVITEC 2024). This competition focused on real world challenges, based on a dataset collected in September 2024 during the Norwegian Jammertest campaign. In this contribution, we present the challenge results, thus describing the scenarios and providing details on the solutions developed by the teams ranked in the top three positions of the competition. Different spoofing conditions were considered in two scenarios, with a total of three problems to be solved with static and/or moving receivers tracking spoofed signals. All in all, the analysis of Carrier-To-Noise Power Spectral Density Ratio (C/N0) values turned out to be an essential element for a proper characterization of the different problems, along with providing a correct identification of genuine GNSS signals that could safely be used by the teams.
