Hi All,
I've been playing with a GPSDO a little here. In order to get a handle
on the response time of the loop, I ran an FFT on the EFC DAC value
over a long run. What was interesting, was that three frequencies
popped up with minor peaks. They were cycles that equaled 512 seconds,
682 seconds, and 1024 seconds.
Is anyone aware of any periods like this in the GPS system? These seem
rather conspicuous!
