How to get NTP to take the time from my GPS device
I am currently attempting to use a USB GPS device to set the time on a Ubuntu 12.04 LTS machine which is not connected to the internet.
If I run gpsmon or xgps it shows me the time, although it’s only seeing one or two satellites at any one time.
If I run ntpq it shows me .GPS. And .PPS. But neither are selected and delay, offset and jitter are 0.
My ntp.conf contains:
driftfile /bar/lib/ntp/ntp.drift
statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable
restrict -4 default kod notrap nomodify nopeer noquery
restrict -6 default kod notrap nomodify nopeer noquery
restrict 127.0.0.1
restrict ::1
server 127.127.28.0 minpoll 4 prefer
fudge 127.127.27.0 refid GPS time1 0.535
server 127.127.28.1 minpoll 4
fudge 127.127.28.1 refid PPS

What GPS RX are you using? USB normally doesn't play well withntp. Unless it specifically says it won't supportPPS(That's a serial line usually) can you also show us the output fromntpq -pcrv
