ESA’s Ariane 6 launch vehicle, on which the deployment of the EU’s Galileo GNSS satellite constellation now depends, has taken another step towards first flight. A fresh series of hot fire tests of the rocket’s upper stage and all-new Vinci engine is now underway at Germany’s DLR center for engine and stage testing in Lampoldshausen.

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.

Robustness to GPS jamming and spoofing is critical for military applications yet challenging, and numerous alternative sensing techniques have been explored over the years. Virtual aiding methods have proven effective, with the ability to constrain and localize the search space for improved operability in GPS-denied environments.

The SAGAIE network was deployed in West-Africa in 2013 to assess the feasibility of an equatorial for ASECNA SBAS by studying ionospheric scintillation. This study of the network’s measurements, taken between 2013 and 2016, analyzes the characteristics of the scintillation recorded by five receivers that cover Sub-Saharan West-Africa.

Speakers at the 14th European Space Conference in Brussels discussed the need to defend EU assets against unfriendly attacks. Recent events in Eastern Europe would seem to lend force to such concerns, as the European Union makes headway toward the intersection of civil infrastructure and security and defense.

Will the network, which some are still fighting, be ready for a September rollout, and if so, what are the implications for GPS and the people who rely on it?
