I don't know what your data looks like of course, but to me it looks like you have a scaling problem. At the very least, I would think you should be in the xE-9 at tau = 1 second. Are you feeding it whole numbers of nanoseconds, but it's interpreting them as milliseconds or something like that?

Yo All! With help from Tom Van Baak and Bob Stewart, I have 6 weeks worth of GPS Serial and PPS timing data in a nice ADEV chart. I think. Check it out: https://rellim.com/graphs/adev.png That is for a SiRF III (MR-350P) with a bad sky view. How does that look? Totally wrong? Somewhat wrong? Once I get this packaged up I'll have lots more similar graphs. RGDS GARY --------------------------------------------------------------------------- Gary E.
