Compact Precision Atomic Clock

ABSTRACT:AOSense proposes to develop a compact precision atomic clock (CPAC) exhibiting excellent short-term stability (better than 110-14 at 1 second of averaging) as well very good mid-term stability (110-16 or better on timescales of 1 day), in a compact, reduced SWaP package suitable for future field applications. The overall volume of the CPAC physics package is <4 l, and the design is suitable for deployment on moving platforms.BENEFIT:Air Force and DoD applications which can benefit from a compact, high precision atomic clock with these specifications are numerous. High stability clocks could improve GPS performance and integrity by reducing noise and the frequency of clock corrections. Advanced radar techniques can benefit from the ultralow phase noise rf and microwave signals provided by optical clocks. Deploying high performance clocks into GPS-denied environments would enable extended mission duration by reducing or eliminating the need for external synchronization.
