Yes, many devices, both professional and amateur,
use a precise 1PPS signal to discipline Qz, Rb, and
Cs frequency standards. Almost every GPSDO on
the market is based on a 1PPS discipline algorithm.

I'm curious about the 10 kHz signal. Can you send
me a pointer to it? Usually 1 Hz is good enough and
in practice most GPSDO use an averaging algorithm
that is more akin to 0.01 Hz to 0.001 Hz.
