![]() ![]() This program could create many of the critical technologies, components, and demonstrations leading to a potential future networked clock architecture. 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. And not only that, but will be more precise and accurate than current atomic clocks last generation. The aim of the program is to study the basic physics of the optical clock principle and to find a way to make optical atomic clocks of low size, weight and power. “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. ROCkN will leverage DARPA-funded research over the past couple decades that has led to lab demonstration of the world’s most precise optical atomic clocks. 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. well now DARPA’s ROCKn program aims to make optical atomic clocks portable. “The goal is to transition optical atomic clocks from elaborate laboratory configurations to small and robust versions that can operate outside the lab,” said Tatjana Curcic, program manager in DARPA’s Defense Sciences Office. ![]() At the end of the program, synchronization between stationary, mobile, and airborne clocks will be demonstrated with timing precision sufficient for 100 GHz distributed coherence. A miniature, highly mobile optical atomic clock enabled by integrated single-photon detectors and waveguide light delivery. nuclear energy, nuclear plant, nuclear power plant, nuclear program. This transportable clock should be able to provide GPS-equivalent, nanosecond precision for 30 days in the absence of GPS. darknet, Darlene Cox, Darlene Walrod, DARPA, Darrell Banks, Darrell Robinson. the second phase focusing on building a larger but still transportable optical clock with unprecedented holdover performance.It will be capable of providing picosecond accuracy for 100 seconds, along with being able to withstand temperature, acceleration, and vibrational noise for use onboard aircraft, vehicles, and satellites and the development of a robust, high-precision, small, portable optical clock that can fit on a fighter jet or satellite.ROCkN consists of two-year phases, taking place over four years: DOCUMENTS REGARDING CHINESE NUCLEAR WEAPONS POLICIES OR PROGRAMS. ROCkN expects to replace GPS atomic clocks with practical, super-accurate optical atomic clocks with low size, weight, and power (SWaP) that can be used outside of the laboratory evironment. 102, 99-F-0112, FOI, PATRICK, SUOSAS PROGRAM, DARPA SOLICITATION MDA972-98-R-0004. DARPA has launched its Robust Optical Clock Network (ROCkN) program with the aim of creating optical atomic clocks to improve time synchronization. ![]()
