Composite USO/CSAC timekeeping system

2012 IEEE Aerospace Conference, 2012
The recent introduction of a first generation of chip scale atomic clocks (CSAC) offers an opportunity to enhance space-based communication and navigation systems with their unique aspects of frequency accuracy and very low size, weight and power. Nonetheless, CSAC frequency noise levels are likely too high to be used directly as master frequency ...

Space CSAC: From Concept to Qualified Product

The Precise Time and Time Interval Systems and Applications Meeting, 2019
Soon after Microchip’s SA.45s Chip Scale Atomic Clock (CSAC) entered production, prospective customers began inquiring about the part’s radiation tolerance. These inquiries resulted in a series of TID tests from 2011 to the present day. It became clear that the standard production CSAC was not a good candidate for LEO applications; the first two CSACs ...
