If you need help with more advanced awk programs, such as correlation or parsing of groupings of multiple NMEA sentences there are some very good awk programmers on this site who will be glad to help.
Ok.
I will try not to give web links in my posts to save your time
Another NMEA thread dealt with NMEA static file.
In my case, I succeeded to connect Bluetooth dongle to my server,
get it connected to Bluetooth GPS device and have gpsd, gpspipe
to read NMEA on-the-fly .
So awk examples gave me a hint how to select records with specified field and print results to stdout.
I would like to learn how basic gps software does work and what data gets from what NMEA sentences, fields, as for tests I need to write basic gps open source software, to discuss some features already known from
more advanced gps applications.
I don't expect to go to data graphical vizualization phase.
But would like to know how awk script can slow down postprocessed
data input. So have to open 2 awk terminal sessions in seperate windows to see how fast awk can process live data stream (pipeline), as in my case.
