The European Space Agency’s (ESA) Navigation Directorate is planning an in-orbit demonstration with new low Earth orbit (LEO) navigation satellites supplementing Europe’s 23 Galileo satellites. The LEO-PNT satellites will investigate a new multi-layer satellite navigation system-of-systems approach to deliver seamless Positioning, Navigation and Timing (PNT). ESA states that the technology could enable much more accurate, robust and available-to-all services.
