Washington University in St. Louis: NSF grant supports development of GPS-free, secure communication

Washington University in St. Louis: NSF grant supports development of GPS-free, secure communication. “Part of modern-day encryption requires precise synchronization of devices. Currently, that’s done using GPS satellites; devices can stay in sync by pinging a satellite at regular intervals. When there is no access to GPS, or if a GPS signal is maliciously jammed or tampered with, there can be no guarantee of secure communications.”
