If you read back through the email chain you'll find Hans' statement concerning 1Hz./µS latency; that's how I became informed of the factor. He did say variable latency which certainly would bring error with it. I'm of the opinion that I do not have variable latency, but rather fixed latency as shown in my most recent email with the 'scope display showing the 1PPS from my Trimble T & the 555 rising output. That latency is on the order of 750nS, and if it's steady in it's timing, shouldn't introduce any error.
My QLG1 arrived yesterday, so I hope to have more insight into the situation soon. I'm interested in seeing what is the cause of the error you're experiencing since, as I understand it, you already have a QLG1 GPS in the lash up.
