“Saying today’s eLoran is what we had in WWII is like saying your 8K Ultra HD television is the same as the 1955 tube set that only got BBC One and ITV. Some fundamentals are the same, but the technology has evolved dramatically.” – U.K. PNT expert.

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.

Israel Aerospace Industries (IAI) has introduced HYPNOSIS, a high-power navigation warfare (NAVWAR) system designed to defend fixed, high-value sites against GNSS-guided aerial threats — chiefly the large drone swarms that have become a defining feature of recent conflicts — by attacking their satellite navigation link rather than shooting them down.
