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.

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 new antenna, measuring just 55 x 55 x 14mm, was trialed in Roke’s own testing facilities, which feature unique, purpose-built, screened chambers.
