Comment on Chip Scale Atomic Clock (CSAC)

4.95 grand a pop, move along folks

For some applications that's not that much. Imagine SpaceX putting one of these in each StarLink satellite and providing their own GPS-like service.

I'm not sure if this clock would be good enough for GPS. It's 3 orders of magnitude less accurate than a cesium clock. But with so many StarLink sats overhead, and synchronizing with more accurate ground clocks, might make up for that.

Let's attach one to a RPi.

I was thinking of putting it in my nixie tube clock, guess not

I did a double take. At first I thought you said ~$5, not ~$5K.
