<div dir="ltr">Kevin,<div>Here is what I see in your data. If your network latency is very low as you say, then it looks like your GPS's don't all have the same time. LaPorte and Crown_Point must be exactly the same as each other and Valparaiso is probably within a millisecond, but lab is way off by about 60 milliseconds (could be somewhere between 41 and 79ms), this is a problem and couldn't be network latency or you would see that in a ping test. And all are about 200 to 280
<span style="text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline">milliseconds different than the NTP time reference that you are using which is not a problem but just effects the debug display. Drain time should be the time that audio is being removed from the buffer and being sent to the transmitter which is sometime in the past as configured by your buffers in the voter.conf. All change in 20ms jumps so a change of 20ms could just be a change of a fraction of a microsecond that incremented from one 20ms buffer slot to the next one. </span><div>

If the pps pulse is 500ms long then it probably would not work at all if it is set to the wrong polarity because the time would be half a second off and I am sure you don't have that much buffer space. Do you know your pps pulse width?

Are all RTCM TX buffers set to the same value? Yes, 480. These values were based upon the math Jim provided, which is a function of maximum latencies on the network. We rarely have greater than 1ms to any host on the network.<br><br><br><br>Are all the GPS's in a location where they cannot be swamped with RF? Yes, and they utilize PCTEL antennas with filtering for use in RF dense environments.<br><br><br><br>Some users have had success with a dedicated RTCM as the master timing source (with no radio connected).

I can infer its meaning, but, one can’t be certain. Any thoughts why the system time is always so far off? It has always been, since I began experimenting with the RTCM in 2012. This is consistent across many RTCM’s.<u></u><u></u></p></blockquote></div></div></div></div></div></div></div><p class="MsoNormal"><br>_______________________________________________<br>App_rpt-users mailing list<br><a href="mailto:App_rpt-users@lists.allstarlink.org" target="_blank">App_rpt-users@lists.allstarlink.org</a><br><a href="http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_rpt-users" target="_blank">http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_rpt-users</a><br><br>To unsubscribe from this list please visit <a href="http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_rpt-users" target="_blank">http://lists.allstarlink.org/cgi-bin/mailman/listinfo/app_rpt-users</a> and scroll down to the bottom of the page.
