Thanks for all the info. I wasn't aware that leapsecond did any testing on the unit. Now I gotta play more with it. Rix Seacord K2AVP Right, I ordered one too when the thread started in November. I just updated the lab report page to include 1PPS risetime and TTL/RS232 NMEA latency/jitter

The SureElectronics unit is general within 10 feet with no observed off the wall excursions. With that in mind, I wonder how accurate is their 1pps output? Hi, There was some discussion on the MG1613S earlier. I ordered one off the bay and did a few test. I tried to post some pics of

The DC468 simulator is not at all picky accept for the one time sentence. I think I looked at the same unit but was thinking about the jitter and accuracy of the 1 pps for a gps controlled oscillator. It was not really apparent, but I think it was not a good choice for that app. Regards Paul. On

Has anyone had any experience with the demo gps receiver being sold on Ebay by Sure Electronics. I have been running one, off and on, for about a month. The stability of its position plots is unbelievable compared to similar plots from Motorola Oncore, Garmin and Trimble Thunderbolt receivers.
