Hi Hal, Thanks so much for the detailed post. I have a follow up question: What is the relationship between the training time and the appropriate value of the time constant (currently set at 18 hours)? The time constant isn't the size of a moving average window is it? Thanks again for your help. We

Re: [time-nuts] Training period for a Rb clock using GPS

Hi The only thing I would add to that is: If your training starts from power up, part of your hour is spent learning something wrong. Most Rb's drift a bit as they stabilize after being turned on. Bob On Jun 2, 2010, at 5:02 AM, Hal Murray wrote: > > par...@berkeley.edu said: >> I am a new

Hello, I am a newbie at this, but have been playing around with 2 prs10s. For our application we need to run the clocks without gps, but we do get to sync it to gps *initially* for as long as we want. However, what we've noticed is that when we train it for short periods of time (< 1 hour a day) th
