![]() ![]() Bill Tang, the original DARPA program manager, now a professor at the University of California, Irvine, also emphasized the importance of military support. This program could create many of the critical technologies, components, and demonstrations leading to a potential future networked clock architecture. Given that the entire market for atomic clocks is on the order of 200 million a year, it would have been hard for industry to supply the funding for this work from internal R&D budgets. "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. "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. 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 Pentagon is pioneering micro technology for just about every device, from 10g video cameras to tiny atomic clocks on a chip David Hambling Wed 19. Our new Robust Optical Clock Network (ROCkN) program aims to provide GPS-quality timing accuracy without GPS. Optical Clock Network (ROCkN) program aims to create optical atomic. However these clocks drift over long timescales making them unsuitable for many applications. The Defense Advanced Research Projects Agency (DARPA) dates back to the launch of. 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. DARPAs Chip Scale Atomic Clock (CSAC) program has developed miniature microwave atomic clocks with extremely low SWaP values (S 16 cm3, W 35 g, P 125 mW) and good short-term stability (10-10 at 1 sec) 3. The technology uses a beam of microwaves to measure the frequency of atoms as they change energy state. Air Americas Sea Technology DARPA Aims for More Accurate Atomic Clock to Replace GPS Inder Singh Bisht Febru2 minutes read The Defense Advanced Research Projects Agency is bidding to develop a 100 times more accurate atomic clock for a range of air, land, and sea platforms. 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. ![]()
