![]() ![]() This program could create many of the critical technologies, components, and demonstrations leading to a potential future networked clock architecture. "If we're successful, these optical clocks would provide a 100x increase in precision, or decrease in timing error, over existing microwave atomic clocks, and demonstrate improved holdover of nanosecond timing precision from a few hours to a month. Supported development of atomic clock technology for commercial, aerospace, and defense applications. "The goal is to transition optical atomic clocks from elaborate laboratory configurations to small and robust versions that can operate outside the lab," Tatjana Curcic, program manager in DARPA's Defense Sciences Office, said in a statement. combine integrated photonics and trapped atoms to enable high-performance, robust, portable atomic clocks and gyroscopes. Typically, optical atomic clocks are large cumbersome machines, but DARPA's ROCKn program aims to make them smaller and lighter so they can be fitted into military vehicles, and even satellites. Optical atomic clocks are so accurate, in fact, that they wouldn't have lost a second over the universe's entire existence of more than 13 billion years. The most accurate type of atomic clock is the optical atomic clock, which replaces the microwaves with a beam of light, boosting the accuracy by a factor of 100. ![]() The Spatial, Temporal and Orientation Information in Contested Environments (STOIC) program seeks to develop PNT systems that provide GPS-independent PNT with GPS-level timing in a. The technology uses a beam of microwaves to measure the frequency of atoms as they change energy state. If successful, PULSE technology could enable global distribution of time precise enough to take advantage of the world’s most accurate optical atomic clocks. ![]() Atomic clocks could provide a solution by allowing field units to tell the time with ultra-precise accuracy, without the need to connect to GPS. ![]()
