One of the GPS modules I'm currently playing with outputs quantization error data in the NMEA data. I can capture the NMEA data and the TICC data - this is not a problem. But I'd really like to be able to capture both datasets in some sort of time-correlated way, so I can easily post-process the TICC data using the quantization error data. I can probably throw something together in Python or C to do this, but before I went through the effort, I figured I would ask if there is a standard tool I haven't been able to find yet which is in common use. So, what is typically used to capture both the NMEA data, and the phase data in a useful way for post-processing? -- - Forrest

In Unix there is the "ts" (aka timestamp) command will be a good start as long as you have newlines (pure NMEA has CRLF at the end of each line but I've come across devices that use other variations). http://manpages.ubuntu.com/manpages/trusty/man1/ts.1.html e.g. I like to use the "%.s" format for ts so that I get epoch seconds (makes my math a lot easier) with fractional second resolution: ts "%.s" hi 1568468896.616954 hi there 1568468897.379812 there this is 1568468898.709839 this is what 1568468899.505906 what im 1568468900.109960 im typing 1568468901.062948 typing Tim N3QE On Sat, Sep 14, 2019 at 9:00 AM Forrest Christian (List Account) < lists@packetflux.com> wrote: > One of the GPS modules I'm currently playing with outputs quantization > error data in the NMEA data. > > I can capture the NMEA data and the TICC data - this is not a problem. > But I'd really like to be able to capture both datasets in some sort of > time-correlated way, so I can easily post-process the TICC data using the > quantization error data.
