Global Navigation Satellite Systems Engineering, Policy, and Design
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.

The US Army released a Request for White Papers (RfWP) to develop new CMFF prototypes. CMFF—C5ISR Modular Open Suite of Standards (CMOSS) Mounted Form Factor—is the Army’s effort to easily and rapidly equip ground vehicles and aviation platforms with capabilities like positioning, navigation, and timing (PNT) and electronic warfare (EW), through capability cards plugged into a common chassis.
