Hi:
We were looking to use an older Trimble Thunderbolt 8 channel GPS receiver for
providing a Stratum 1 time reference. I realize this is discussed on the ntp.org
web site but sadly, the link to Trimble to get the driver (any any ntp driver)
are now all dead links.
We have it connected to a Linux host running Linux (RH 6.6) and we see the
receiver. However, it is not providing any useful data to for the NTP
application to use. We have used the configuration examples in the ntp.org site.
When you do a ntpq -p, you see the source but it is never used (lacking the "*"
to indicate it is active as the primary reference). We do understand the Trimble
Thunderbolts can not be "polled" since it is lacking any firmware that supports it.
# ntpq -p
remote refid st t when poll reach delay offset jitter
==============================================================================
GPS_PALISADE(0) .GPS. 0 l - 32 0 0.000 0.000 0.000
*kona.xxxxxxx.xx 216.218.254.202 2 u 81 128 377 0.491 3.889 0.599
Is there anyone with the prior experience in getting these older Trimble units
to work? Most of the information dates back to the early 2000's or so.
Our desire is to get away from using an external Internet based public NTP site
to limit possible security issues.
Thanks.
Kevin
