Since these infrastructures have become primary users of Positioning, Navigation and Timing (PNT) services, the availability of backups or Alternative PNT (A-PNT) infrastructures should be considered as a priority to mitigate the impact of a potential disruption of GNSS. This report presents the results of a test campaign, conducted at the European Commission (EC) Joint Research Centre (JRC), Ispra. It was aimed at assessing the performance of A-PNT demonstration platforms. This testing and performance evaluation assessment activity were conducted, in the framework of a Call for Tender launched by the Directorate General for Defence Industry and Space (DEFIS) of the EC. Over eight months of testing activities, the selected A-PNT platforms were evaluated at the JRC premises, and in a few cases, also at other locations, as agreed with the A-PNT platform providers. Such demonstrations showcased precise and robust timing and positioning services, in indoor and outdoor environments. The results of the test campaign showed that all A-PNT platforms under evaluation demonstrated performances in compliance with the requirements set. }, title = {Assessing Alternative Positioning, Navigation and Timing Technologies for Potential Deployment in the EU}, type = {Scientific analysis or review}, url = {}, doi = {10.2760/596229 (online)} }
