This is in effect a really complicated way of getting an analog readout of his cesium fountain.
The chain adjuster was interesting, though.
Another very accurate pendulum clock (this one solar disciplined): https://en.wikipedia.org/wiki/Clock_of_the_Long_Now https://en.wikipedia.org/wiki/Clock_of_the_Long_Now
- wbl 2y agoNot really: look at the Alan curves. This is a disciplined PLL with a fairly slow loop. Most of the accuracy at short time scales is from the pendulum it's only the long term stability that the atomic clock impacts.
- avidiax 2y agoAll of the accuracy is from the pendulum. The author hasn't implemented a correction for the integral error yet.
