Mine is also 23898 bytes. I've tried connecting on different days (i.e. I should be seeing different satellites), and the file always remains the same size, and has the same headings. The data does change though, so there's something going on there (i.e. it's not *just* the customer config data that gspdriver talks about).

Also note that the gps_last_saved_report file is 14000bytes long, which is quite large for a file which need (presumably) only save the lat and long coordinates. Therefore it may be that this file stores the alamnac/ephemeris data.

Another thing to note is that this latter file is mostly filled with 0x00; seems strange to write lots of 0x00 to a file when not writing them would achieve the same end. Perhaps waiting for some kind of upgrade/enable to write useful almanac/ephemeris data?
