The Chip-Scale Atomic Clock (CSAC) program created ultra-miniaturized, low-power, atomic time and frequency reference units.
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 use of CSAC technology can greatly improve the mobility and robustness of any military system or platform with sophisticated UHF communication and/or navigation requirements.
This program resulted in commercially available CSAC technology. The CSAC program achieved a 100-fold size reduction while consuming 50 times less power than traditional atomic clocks.
