@ -3,7 +3,7 @@ This app allows you to broadcast GPS baseband signal data streams.
## Generator
You can use [gps-sdr-sim](https://github.com/osqzss/gps-sdr-sim) to generate data for this app.
`gps-sdr-sim -e RINEX_NAVIGATION_FILE -l LAT,LONG,HEIGHT -o SOMENAME.C8`
`gps-sdr-sim -e RINEX_NAVIGATION_FILE -l LAT,LONG,HEIGHT -b 8 -o SOMENAME.C8`
That will create `SOMENAME.C8`, but note that you also need to specify its sample rate and frequency in another file, as explained below.
@ -21,7 +21,7 @@ This file should use the same filename as the .C8 file but with .TXT extension.
## Example 1
Create a rather small polygon with a path in KML format (i.e. a path you might want to simulate to walk). You can use Google Earth or another solution like https://www.doogal.co.uk/polylines.php. Load that file in the free [SatGen NMEA simulator](https://www.labsat.co.uk/index.php/en/free-gps-nmea-simulator-software). In the generator, change the frequency to 10 Hz and export the NMEA.
`gps-sdr-sim.exe -e brdc1180.20n -g NMEA.txt -o TESTGPS.C8`
`gps-sdr-sim.exe -e brdc1180.20n -g NMEA.txt -b 8 -o TESTGPS.C8`
You also need to create `TESTGPS.TXT` as specified above.
