Hi there, I am trying since some time to attach a SkyTraq Based GPS receiver to a serial port + pps which "basically" works fine by using gpsd 2.92 and ntpd 4.2.4p8.
Still I get "time resets" every some hours which I do not really understand: i get less time resets (+1 sec ... -1 sec) when I configure only pps via shm. Configuring gps + pps via shm even gets worse... Ok, not to bother you with support requests on old version, I will go for the actual release and therefore I have a few questions: a) can I use PPS there without the PPSAPI? I do not really want to build a new kernel... having a short look it seems that there is no PPS support for the SHM interface (anymore?)? b) could somebody hint me to a working ntp.conf for nmea gps + pps and no external ntp servers? c) I did convince somebody at SkyTraq to provide me also a special NMEA sentence for discovering leap seconds, AFAIS I have to modifiy refclock_nmea.c in the same way as done for the GARMIN devices... Sorry if my questions are not precise enough but some answers could make me save a lot of work :-) Thanks & Br Steve _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
