    I try to use GPS module with usb as NTP server by :
    server 127.127.28.0 noselect
    fudge 127.127.28.0 time1 0.035 refid GPS

    server 127.127.28.1 prefer noselect
    fudge 127.127.28.1 refid PPS
    and start gpsd with :
    gpsd -n -D 5 /dev/ttyUSB0
    but it only has gps value and no PPS value (my device support pps). and this value has a few mileseconds delay. Dose anyone know how to get high accuracy time or pps time from my GPS module?
