Hello all, I posted the following on the timekeepers mailinglist, but I got an advice to publish it here too.
----- My Rockwell "Jupiter" Global Positioning System (GPS) Receiver (Part No. TU30-D140-221/231) results in errors when placed into 'Zodiac Binary Protocol mode' with ntpd in conjunction with Linux(PPS) and/or FreeBSD. In clockstats the following is visible: PIN J1-8 = low 54627 44849.102 127.127.31.0 gpos: Navigation solution not valid 54627 44849.642 127.127.31.0 pulse: jupiter_parse_t: Unknown gweek PIN J1-8 = high: 54627 44989.341 127.127.31.0 gpos: Navigation solution not valid 54627 44989.453 127.127.31.0 unknown message id 1002 54627 44989.861 127.127.31.0 pulse: jupiter_parse_t: Unknown gweek In NMEA mode (PIN J1-7 = low) the receiver works, but has the 'random-second-skew' problem as reported in the driver pages from Dave Mills (driver31). In both this page and the refclock_jupiter.c source I could not find a lead to the author of this Jupiter driver. Anyone familiar with this?
