These scripts are intended to extract GPS Broadcast Ephemerides from a uBlox GPS, and output them in a RINEX Navigation Data compatible format.
This is primarily intended to provide an 'offline' alternative to the CDDIS-supplied broadcast ephemeris files, as required by the RS Vaisala RS92 Radiosonde decoder.
A lot of this repository is borrowed from tridge's pyUblox codebase.
Usage:
$ python ublox_ephemeris.py -p /dev/ttyUSB0 -b 115200 -o ephemeris.dat
NOTE: This is still a work-in-progress, and the RINEX output is currently un-usable due to missing fields.
