The European Space Agency’s new navigation head, Francisco-Javier Benedicto Ruiz, has a lot to say about GNSS, both present and future. We recently spoke with him about his views on satellite navigation, signal vulnerability and authentication, and the agency’s working relationship, or not, with Russia. The technical team behind the Galileo authentication service and industry representatives developing alternative positioning, navigation and timing solutions also share insights.
