Every year... always makes me wonder, do these vendors even test this themselves? I know at least one vendor who disn't have GPS simulators and relied on Trimble's built-in test mode - which gives you 13-bit week counters, whereas the satellites give you 10-bit counters. So the vendor assumed 13-bit and was comparing the current wc to 13-bit that never came. Luckily I found the issue months before the event, and only because we purchased GPS simulators - which I recommend to anyone running timing services in production.
Oh well, at least this keeps us busy.

Any estimate on when they will ship new firmware? We just finished replacing our previous gear with this a week ago; timing is everything. :) Vendor was contacted yesterday and have supplied a patch this morning to reduce the GPS->UTC offset back to 17 until they get a more permanent fix from Trimble. I've not installed it yet, but the vendor states the patch won't persist across reboots. --n _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
