The long-range navigation (LORAN) system, introduced during World War II, continues its ascent as a potential complement to GNSS services, especially in indoor, urban and underground scenarios. The UK-based Roke company, with support from the European Space Agency (ESA), is working to bring enhanced LORAN (eLORAN) to a broader user base, developing a miniaturized eLORAN antenna for portable and even hand-held devices.

On 30 July 2024, European navigators commemorated the 90th anniversary of Guglielmo Marconi’s first demonstration of microwave-guided navigation. In the Bay of Silence, off Sestri Levante, Italy, the historic vessel Leudo performed a blind navigation maneuver, crossing the space delimited by two buoys, guided by radio impulses transmitted from the shore. The operation was, in effect, a reenactment of radio pioneer Marconi’s demonstration of 30 July 1934.
