The goal of the Defense Advanced Research Projects Agency’s (DARPA’s) Chip-Scale Atomic Clock (CSAC) program is to provide warfighters with enhanced radio communications and jam-resistant navigation ...
DARPA has announced a new initiative called the Robust Optical Clock Network (ROCkN) program, which will look to develop a practical, super-accurate optical atomic clock that is robust and small ...
Small timekeeping errors can lead to substantial problems for many applications that depend on precise timing. For example, radio navigation systems, such as GPS, work by comparing the time it takes ...
The heart of a minuscule atomic clock—believed to be 100 times smaller than any other atomic clock—has been demonstrated by scientists at the Commerce Department’s National Institute of Standards and ...
