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.”

The European Space Agency (ESA) has initiated two innovative navigation missions, Genesis and LEO-PNT, as part of its FutureNAV program, with contracts totaling €233 million awarded to several European entities. This strategic move is aimed at addressing the growing demand for more resilient and precise navigation solutions in Europe.
