- mastax 1y agoFinally a good use case for the chip-scale atomic clock. https://www.microchip.com/en-us/product/csac-sa65 https://www.microchip.com/en-us/product/csac-sa65
- nullhole 1y agoHeh, my thoughts exactly! Those chips are also useful for getting better positions from navigation signals. One could imagine using them to help filter out spoofed signals, for example.
- nullhole 1y agoThey exist[0], but aren't cheap (~$1400 US/chip for the base model). [0] https://www.microchip.com/en-us/products/clock-and-timing/components/atomic-clocks/embedded-atomic-oscillators/mac https://www.microchip.com/en-us/products/clock-and-timing/co...
- tverbeure 1y agoRubidium oscillators are atomic clocks the way PhDs are doctors! (Don't worry, I know they are considered atomic clocks, I have 2 Rb modules.)
