Hi, Note that the 1804M, also has a 1PPS output. This is coming directly from the GPS module 1PPS. The Trimble SV6 module I have in my units is only good to 1us, almost a 1000 times worse than a Tbolt. I am not sure if the SV6 has a "sawtooth" error message giving a good estimate on how wrong the current 1PPS pulse is/was. However improving the 1PPS output accuracy and jitter could for some uses be a useful mod.
