In this episode of DARPA’s podcast series, Voices from DARPA, join program manager Lin Haas of the Agency’s Strategic Technology Office as he shares his expansive view on the current and future roles of Positioning, Navigation, and Timing (PNT) technology, whose most famous incarnation is known as the Global Positioning System (GPS). Haas reveals ambitious PNT programs that include efforts to develop an undersea system that provides omnipresent positioning capabilities across ocean basins where GPS signals do not go and to exploit environmental signals, such as the electromagnetic features of lightning, for back-up geolocation service if GPS were to become unavailable. You will also learn how a guy ends up with the name Lin.
