DHS S&T demonstrates precision timing technology
It was announced on 20 April in Washington that the Department of Homeland Security, Science and Technology Directorate (S&T) had conducted a successful demonstration of the Enhanced Loran (eLoran), a precision-timing technology for financial transactions at the New York Stock Exchange (NYSE).
eLoran is a low-frequency, high-power radionavigation signal that is broadcast by ground-based transmission stations, allowing the signal to penetrate through buildings and provide precision timing indoors and throughout urban environments.
