![]() This clock should be capable of providing picosecond (one-trillionth of a second) accuracy for 100 seconds and must be able to withstand temperature, acceleration and vibrational noises. AugSource: University of Sussex Summary: Researchers have solved a major stumbling block in the development of portable atomic clocks, by working out how to reliably switch on. ![]() Previous DARPA ROCkN optical atomic clocks will enable multidomain synchronization among various platforms, multi vehicle swarms. The first phase will involve developing a robust, high-precision small portable optical clock that can fit on a fighter jet or satellite. Making clocks this precise portable could improve upon existing military systems such as GPS, and potentially enable entirely new radar, LIDAR and metrology applications. The programme will consist of two separate phases. “This programme could create many of the critical technologies, components and demonstrations leading to a potential future networked clock architecture.” WASHINGTON: The Defense Department’s cutting-edge tech research agency is seeking industry partners to develop laser-based clocks that will be 100 times more accurate than today’s most precise. “If we’re successful, these optical clocks would provide a 100-fold 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. DARPA Defence Sciences Office programme manager Tatjana Curcic said: “The goal is to transition optical atomic clocks from elaborate laboratory configurations to small and robust versions that can operate outside the lab.
