Suggestion for a timing GPS receiver (Trimble / Ublox / other?)

The Trimble ... it is a newer design..  The Oncore is getting rather long in the tooth and some have GPS week rollover issues.  The Trimble has a higher clock rate and less 1PPS jitter.


Which would be the preference as timing receiver Motorola Oncore or a Trimble Resolution T ?

Thanks, forgot I have a Jupiter-T (D-120?) in my parts box , on that note out of the two Trimble vs Jupiter-T. I think the Jupiter has a jitter of around 15ns, not sure what the Jupiter-T specs but I believe 10-20ns.

Hi

The target application is NTP with the PPS probably coming in via a RS-232 serial port.
Anything that jitters less than 200 ns is probably going to look “same / same “.
