Today, the patent is in the public domain, which means it can be used without being licensed. The goal is to create low-SWaP optical atomic clocks. This patent covers the invention of the chip-scale atomic clock, a spinoff chip-scale atomic magnetometer, and silicon micromachining of the vapor cell that contains the atoms in both devices. 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. Our new Robust Optical Clock Network (ROCkN) program aims to provide GPS-quality timing accuracy without GPS. 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. To address this scenario, DARPA has announced the Robust Optical Clock Network (ROCkN) program, which aims to create optical atomic clocks with low size. DARPA has launched its Robust Optical Clock Network (ROCkN) program with the aim of creating optical atomic clocks to improve time synchronization. The first phase will involve developing a robust, high-precision small portable optical clock that can fit on a fighter jet or satellite. This kind of technology is entering the prototype stage on the DARPA Atomic Clock with Enhanced Stability (ACES) program, while the foundations of portable and larger clocks with higher. The programme will consist of two separate phases. 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.1 ROCkN clocks will not be as precise as the best lab optical clocks, but they will surpass current state-of-the-art atomic clocks in both precision and holdover while maintaining low SWaP. 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. “This programme could create many of the critical technologies, components and demonstrations leading to a potential future networked clock architecture.” Our new Robust Optical Clock Network (ROCkN) program aims to provide GPS-quality timing accuracy without GPS. “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.
