The above is technically correct but if you find that Internet pool
servers are seriously out performing your GPS, then maybe you need a
better GPS.
Your're misunderstanding the problem. NTP won't use the
much-better-than-Internet PPS signal without an associated clock which
delivers TOD. My understanding is that the mindist ensures that the
serial (NMEA) time source, the "prefer" peer, isn't set to falseticker
due to high jitter (which would make the associated PPS source one,
too.) As I already cited and quoted: "the prefer peer can still be
discarded by the intersection algorithm as a falseticker. To avoid
this, it is usually wise to increase the mindist option of the tos
command from the default .005 s to something like .05 s."
So, a pool server may be outperforming the serial TOD source, but it's
not outperforming a reasonable PPS source, so there isn't a problem.
The solution is correct practically and technically.
