As I said, Without a PPS signal you will not get reasonable results. If
the GPS lacks the PPS get another GPS. They are cheap. Really nice units

for $20 to $30.
The problem with NMEA only setups is that (I think) the f

Any sugguestions?

They are well within the allowable error bands, given the measured root

32 ms!
The delays are due

Hi all!
I have two internal FreeBSD with GPS receivers attached (Garmin 18 LVC:
10.0.2.10 / Sure Evaluation Board:10.0.2.9). Both machines are on the same
LAN segment (VLAN).
For redundancy, I've configured a Cisco switch as a stratum 2 server. Here's
the relevant information:
$ ntpq -pcrv 10.0.
