![]() ![]() 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 in a robust package. ![]() 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. To address this scenario, DARPA has announced the Robust Optical Clock Network (ROCkN) program, which aims to create optical atomic clocks with low size, weight, and power (SWaP) that yield timing accuracy and holdover better than GPS atomic clocks and can be used outside a laboratory. DARPA’s Atomic Clock with Enhanced Stability (ACES) program is exploring the development of next-generation, battery-powered CSACs with 1000x improvement in key performance parameters over existing options. If GPS were jammed by an adversary, time synchronization would rapidly deteriorate and threaten military operations. A timing error of just a few billionths of a second can translate to positioning being off by a meter or more. High-tech missiles, sensors, aircraft, ships, and artillery all rely on atomic clocks on GPS satellites for nanosecond timing accuracy. five-things-to-know-about-nasas-deep-space-atomic-clock T23:58Z. 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 development of CSAC enabled ultra-miniaturized and ultra-low power atomic clocks for high-security Ultra High Frequency (UHF) communication and jam-resistant GPS receivers. The technology challenge specified in the three-phase program, budgeted for up to 50 million, is to design and build a new generation of palm-sized, battery-powered atomic clocks that perform up to 1,000 times better than the current generationwhich itself is the outcome of previous DARPA efforts, including the Chip-Scale Atomic Clock (CSAC. Synchronizing time in modern warfare – down to billionths and trillionths of a second – is critical for mission success. To address this scenario, DARPA has announced the Robust Optical Clock Network (ROCkN) program, which aims to create optical atomic clocks with low size, weight, and power (SWaP) that yield timing accuracy and holdover better than GPS atomic clocks and can be used outside a laboratory. ./press-release/new-nasa-science-live-program-premieres-this-week. CSAC The Chip-Scale Atomic Clock (CSAC) effort created ultra-miniaturized, low-power, atomic time and frequency reference units. ![]()
