There are sudden increases in noise (bursts that last from seconds to minutes) on the plots I posted.
I believe the sudden and drastic increase in noise at times comes from the GPS loosing lock. At the moment, I cannot hook up the computer to the GPS and verify, but I will do that later. In the actual GPSDO implementation, I will have to find a reliable way to detect that condition and freeze the drive to the EFC. I am not sure how to do that with the Jupiter other than decode the serial data with a uC and turn the thing off when there are not enough satellites.
