Hi all. I'm using this GPS module with a MTK3339 chipset. Bought from here: https://www.adafruit.com/product/790 And I'm using ntpd with have PPS support compiled-in.
Juergen, thanks for pointing out the documentation. I've understood more about NMEA receivers now. I've tried Brian's and Juergen's server and fudge configuration, using time2 to align with the NMEA data-stream and now getting better results. I don't have a scope, so how do you suggest I determine the correct values to use for time2 ? server 127.127.20.0 mode 17 prefer minpoll 4 maxpoll 4 fudge 127.127.20.0 flag1 1 flag3 1 time2 0.500 # pps kernel msg offset .5s remote refid st t when poll reach delay offset jitter ============================================================================== *GPS_NMEA(0) .GPS. 0 l 15 16 377 0.000 -49.176 25.007 +time.sunrise.ne 195.141.230.78 2 u 22 64 377 8.357 114.864 17.534 +192.33.214.47 129.194.21.195 2 u 23 64 377 13.382 115.777 18.286 +ntp0.as34288.ne 85.158.25.74 2 u 32 64 377 6.914 113.929 17.013 +eudyptula.init7 217.147.223.78 3 u 26 64 377 9.683 115.067 17.673 regards.
