Hi David,
I've had a detail look into your freeBSB configurations for ntp.
Unfortunately im constrainted Debian as my operating system. Perhaps
could you let me know of your ntp version. I've ran the ntpdc -c kern
command, my output is:
DebianSleek:/home/sleek/GPS# ntpdc -c kern
pll offset: 0 s
pll frequency: 0.424 ppm
maximum error: 0.019472 s
estimated error: 1.6e-05 s
status: 0040 unsync
pll time constant: 0
precision: 1e-06 s
frequency tolerance: 512 ppm
pps frequency: 0.000 ppm
pps stability: 512.000 ppm
pps jitter: 0.0002 s
calibration interval: 4 s
calibration cycles: 0
jitter exceeded: 0
stability exceeded: 0
calibration errors: 0
The values above don't change at all, besides the "maximum error:
0.019472 s" value. The values associated with the pps doesn't change
at all. So if you have any links or web sites that could assist me
getting my device to work. I've drop using the gpsd share memory
driver and is just using the generic driver. With a failure attempt
of using the PPS driver provided by the ntpd. Ie the 127.127.22.0.
Your help will greatly appreciated. I know your a expert at working
with this device. Your advice will be greatly value. And i thank you
in advance.
Cheers,
Sleek
Sleek,
My equivalent output is:
pll offset: 1.634e-06 s
pll frequency: 41.542 ppm
maximum error: 0.025836 s
estimated error: 7e-06 s
status: 2107 pll ppsfreq ppstime ppssignal nano
pll time constant: 6
precision: 1e-09 s
frequency tolerance: 496 ppm
pps frequency: 41.542 ppm
pps stability: 0.006 ppm
pps jitter: 1.567e-06 s
calibration interval: 256 s
calibration cycles: 61418
jitter exceeded: 422360
stability exceeded: 0
calibration errors: 16
Fron an "ntpq -c rv" I get:
status=24f4 leap_none, sync_uhf_clock/PPS, 15 events,
event_peer/strat_chg,
version="ntpd 4.2.0-a Sun May 8 06:01:21 UTC 2005 (1)",
processor="i386", system="FreeBSD/5.4-RELEASE", leap=00, stratum=1,
precision=-16, rootdelay=0.000, rootdispersion=1.918, peer=58409,
refid=PPS, reftime=c87c1138.2d0e0a40 Thu, Aug 3 2006 7:07:52.175,
poll=6, clock=c87c1139.e32f3a50 Thu, Aug 3 2006 7:07:53.887, state=4,
offset=0.001, frequency=41.542, jitter=0.001, stability=0.004
I hope that helps. I'm not an expert but a novice at this OS and NTP
application, and needed some help to get this working, as I acknowledge on
my Web page. The "status: 0040 unsync" suggests that either the serial
component of the GPS signal or the PPS part is not getting through. What
does "ntpq -p" show?
Cheers,
David
