DARPA to Develop Advanced Tiny Chip-Scale Atomic Clocks for Military PNT Applications
Defense Advanced Research Projects Agency (DARPA) is presently working on an advanced version of its first-generation, battery-powered, miniature chip-scale atomic clock (CSAC) with 1000x performance improvements for positioning, navigation, and timing (PNT) applications. DARPA’s Atomic Clock with Enhanced Stability (ACES) program aims to build the next-generation atomic clock owing to the limitations of the now
