Symmetricom history
Symmetricom company history timeline
NIST inventor John Kitching began working on parts of the CSAC technology in 1999.
In 2001, DARPA funded a program to develop a commercial CSAC in support of military needs for secure wireless communication and jam-resistant GPS receivers.
They were first developed by the Defense Advanced Research Projects Agency (DARPA) and the National Institute of Standards and Technology (NIST) in 2004.
NIST’s funding for the effort ended in 2006, and Kitching went on to develop other devices such as magnetometers, photonically integrated wavelength references and chip-scale atomic clocks operating at optical frequencies, which could offer higher performance.
The first commercial version is this cesium CSAC with model number SA.45s, produced by Symmetricom, Inc., in Beverley, Mass., and sold beginning in 2011.
