The European Space Agency (ESA) HydroGNSS Scout mission has officially completed its eight-month commissioning phase, now entering full scientific operations. The two-satellite constellation represents a significant leap forward in utilizing GNSS reflectometry (GNSS-R) for remote sensing. By leveraging passive bistatic radar principles, the mission captures and analyzes L-band signals originally transmitted by GPS and Galileo navigation satellites.

The European Space Agency (ESA)-funded project ‘A White Rabbit based implementation of Coherent Clock’ has successfully completed its validation phase. The project demonstrated a highly resilient, ground-based time distribution system designed to safeguard critical infrastructures against GNSS vulnerabilities. Funded under ESA’s NAVISP program, the initiative was led by Safran Electronics and Defense Spain.

The European Space Agency (ESA)-funded PARTICLE project has demonstrated a multi-layered approach to assured positioning, navigation and timing (PNT), combining authenticated Galileo signals, receiver-based anti-spoofing and security enhancements for 5G positioning. Funded under ESA’s NAVISP program, the activity was led by Qascom, with partners Loctio and the University of Patras.
