Re[2]: NTPsec reports excessive jitter from GPSD/KPPS SHM

[Nick Burkitt]

Hi Gary.

Except, you have them backwards. Your PPS is on SHM(0) and your

GPS is on SHM(2). Assuming: gpsd -n /dev/pps0 /dev/ttyACMx

Why assume? I included the gpsd command line. Here it is again:

With this command line:

gpsd -n /dev/ACM4 /dev/pps0

and this ntp.conf GPS/PPS configuration:

# GPS Serial data reference (NTP0)

 refclock shm unit 0 refid GPS noselect

 # GPS PPS reference (NTP1)

 refclock shm unit 2 minpoll 3 maxpoll 3 refid PPS prefer
