A value of 0 for NP, 0 for Span, 2000.000 for Freq Skew and
4000ms for Std Dev are clear indications that the source is not being
tracked.

Hi,
I am running chrony 4.3 on an Asus RT-AX86U Pro router which acts as
server for my local network. No matter if I use
a) remote ntp servers
b) a network client Raspberry Pi with GPS module as sole server
c) that Raspberry synchronised to the same publich servers as in a) as

No, I still have them in the current config just to be able to compare
the router's time obtained from a local GPS receiver with the "official"
public servers.
Daniel's config solved the problem. As written in my repsonse to him I
am not fully sure but think that removing "maxupdateskew" and/or
Thanks you, Daniel! It's working beautifully now. Not sure what did the
trick. During the past weeks I also tried to poll more often and apply
the median filter similar to your server line but it did not improve the
offset. Following your config I removed the "maxupdateskew" line and

Hi,
until last week my Raspberry Pi was querying a handful of ntp servers.
Seeing offsets of mostly +/-20ms and up to +/-200ms I wondered if I
could improve this and got an Adafruit Ultimate GPS module (USB
connector with additional PPS pin). The NMEA data is polled via
/dev/ttyUSB0 whereas
Bryan, many thanks for the explanation and the suggestion regarding
SHM0. My only worry is that the sourcestats output is not offering much
in terms of offset of the network sources:
$ chronyc sourcestats
Name/IP Address NP NR Span Frequency Freq Skew Offset
Std Dev
will ask on snbforums.
Many thanks for your support!
