Ariane 6’s inaugural rocket launch took place from Europe’s Spaceport in French Guiana at 16:00 local time on 9 July. It has taken over from Ariane 5, featuring a modular design that can launch missions from low-Earth orbit and into deep space. Galileo Second Generation (G2) satellites are projected to join the constellation in 2026 with the Ariane 6 launcher. G2 satellites will use electric propulsion and host a more powerful navigation antenna, better atomic clocks and fully digital payloads.

The European Space Agency (ESA) has successfully executed a substantial upgrade to the ground segment of the Galileo satellite navigation system, achieving this milestone without any disruption to its users. This update enhances the Galileo Control Segment responsible for managing the constellation of orbiting satellites.

A novel approach for GPS M-code pull-in. Signal acquisition and tracking are two essential functions of a satellite navigation (satnav) receiver that allow it to form a position, velocity and time (PVT) solution.

It has been widely demonstrated that GNSS-based localization technologies are vulnerable to signal jamming and spoofing/replay attacks, where a receiver can be either denied positioning or deceived to compute a forged PVT solution. Today, it is possible to spoof a GNSS receiver to any arbitrary location and time in the world with many incidents being reported in the wild.

Galileo satellites GM25 and FM27 were successfully launched into orbit from Kennedy Space Center in Florida on April 27. Thierry Breton, Commissioner of the Internal Market of the European Union, confirmed via X, “2 new Galileo satellites successfully launched last night. Awaiting Ariane6, the 2024 launches are crucial for Galileo’s resilience, robustness and continuity of its civilian & military applications. Galileo deployment will continue in 2025.”
