HI, everyone!

I wanna know the GPS log format, and extract data from ulog file.

Are these the RINEX format? If these the RINEX, I can POST analysis, amn’t I?

And how can I extract GPS log data from ulog file? Should I use the pyulog?

Thank you!

Hi

Yes, pyulog is the right tool to extract data. You can use it to convert to a CSV file for example: https://github.com/PX4/pyulog#convert-ulog-to-csv-files-ulog2csv.
The gps data is in the vehicle_gps_position message: https://github.com/PX4/Firmware/blob/master/msg/vehicle_gps_position.msg
