Hello All,
I've (temporarily) given up on the idea of using Linux for the OS, and
moved to FreeBSD, with the same GPS hardware, using some of the
information on this web page:
http://www.satsignal.eu/ntp/FreeBSD-GPS-PPS.htm
ntpq -p now says:
remote refid st t when poll reach delay offset
jitter
==============================================================================
*dns1.rmplc.co.u 195.66.241.3 2 u 25 64 1 6.889 1.226
0.615
91.220.127.250 130.88.200.6 3 u 24 64 1 5.600
4.940 0.274
GPS_NMEA(1) .PPS. 0 l 39 64 1 0.000
0.826 0.001
So, I *think* that everything is okay, and it is using the PPS signal.
There is one slight worry, which is what I see in /var/log/messages:
Feb 2 09:50:16 tock ntpd[1573]: refclock_nmea: time_pps_kcbind failed:
Operation not supported
Please note, I have not done any recompiling of the kernel at this stage
- just using the GENERIC kernel, because after reading the comments from
Per Hederland in the System software customisation section of the above
web page, it seemed unnecessary. Comments?
Thanks for your help!
Paul.
