On 13 January 2026, Europe’s Copernicus Earth-observation program carried out a planned reconfiguration of the GNSS receiver aboard the Sentinel-3B satellite, a low-profile engineering activity that nevertheless illustrates how deeply Galileo-based positioning and timing now underpin European Earth-observation services.

Europe’s role in lunar exploration has crystallized around a clear strategic theme: enabling reliable positioning, navigation and timing (PNT) beyond Earth, in close coordination with international partners, particularly NASA.

Europe has found an intriguing new player in the contest to strengthen resilience in positioning, navigation, and timing (PNT). iNGage is a Franco-Italian startup formed in early 2025 to commercialize a novel class of micro- and nano-electro-mechanical systems (M&NEMS)-based inertial sensors.
