The European Space Agency (ESA) has confirmed plans to launch the first two satellites in its low-Earth orbit (LEO) positioning navigation and timing (PNT) constellation in the second half of December 2025. The launch will use a Rocket Lab Electron Vehicle, marking Europe’s first venture into LEO-based satellite navigation.

The LEO-PNT in-orbit demonstrator mission, called Celeste, aims to …

The E-GIANTS (European GNSS Improved Authentication Solutions) project was commissioned by the European Commission and technically supervised by EUSPA. The project responds to the growing threat posed by quantum computing to traditional cryptographic methods, which could compromise the security of GNSS services in the coming decade. The study highlights that while quantum computers threaten classic asymmetric cryptography …
