Lasy Heather can read a receiver data capture file as a "simulation" file. Use the /rs=filename command line option. You can also specify the /0 command line option (don't use serial port) and /rx= command line option to specify the receiver type. The simulation file reads in at around 20-30 times faster than real time (goes faster when the mouse cursor is kept out of the plot area),
------------------ >First is to collect the data. I have a python script that grabs everything from a NMEA device and logs each line with a time stamp. The GPS orbit period is 12 hours so you need 12 hours of data to see everything. But there are 30 satellites, so a few hours will show the hole. The next step is to extract the data into a useful format. That's another python script. Then, just feed that to gunplot. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
