Good chips aren't that hard to get. If the datasheets are to be believed: Trimble Lassen iQ 50ns Trimble Resolution-T 15ns ublox Antaris4T 50ns,15ns compensated NavSync CW25-TIM 25ns SigNav TM3-01 10ns NavSync CW12-TIM 30ns Motorola OnCore UT+ 50ns Motorola/iLotus/Synergy-GPS M12M 20ns, 6ns corrected -- GDB has a 'break' feature; why doesn't it have 'fix' too? _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
