What are the current use cases for atomic clocks?
- formerly_proven 6y agoAdjusting clocks that aren't atomic. Cellular base stations used to have rubidium sources disciplined to GPS as a reference frequency for synthesis. AIUI, put the expensive, precise part in the base station, have the cheap handset lock onto that. Free accuracy. Not sure if they still do it that way. That's where all the cheap used rubidium sources on eBay come from.
- SAI_Peregrinus 6y agoAlso GPS (and other GNSS system) satellites themselves have atomic clocks.
- tyingq 6y agoLow latency time source for stuff like Spanner that appreciates times that are the same across disparate data centers?
- jdsully 6y agoThey have applications in the database space, e.g. see Google's spanner: https://www.theverge.com/2012/11/26/3692392/google-spanner-atomic-clocks-GPS https://www.theverge.com/2012/11/26/3692392/google-spanner-a...
