Satellite navigation is a ubiquitous presence in all our lives, employed for so much more than simply transportation, from precision farming to managing power grids, financial trading to communication links. Signals from space are processed through complex mathematical models using highly precise algorithms to yield centimetre-level accuracy – under optimal signal conditions.

ESA’s Navigation Innovation and Support Programme, NAVISP, seeks to improve European competitiveness across the entire Positioning, Navigation and Timing, PNT, domain by developing novel products, systems, and services. One way to do this and make satnav performance even better is by combining Global Navigation Satellite Systems, GNSS, with other technologies, from inertial sensors and machine vision to 5G and 6G and now, increasingly, Artificial Intelligence – AI.
