But why not just ignore bad sentences?
Easier to fix your GGA, set sats used to 4. One line of sed could
do that.
Should it be understood that gpsd ignore checksum?
Nope, you would have to also fix the checksum. But that is easy.
Heh. The gpsbabel sets count of satellites on GGA sentence to 00 string
in principle: https://www.gpsbabel.org/htmldoc-development/fmt_nmea.html
I do not know why this is so.
I updated my log player to add a number of satellites to the GGA
sentence on the fly. With recalculate checksum, of course.
Well, logs, created by gpsbabel, played smoothly.
But I confused:
This https://gpsd.io/NMEA.html#_gga_global_positioning_system_fix_data
approved that number of satellites are a string of two digits. I write
one digit by mistake -- and gpsd accept this.
I think this is correct, but perhaps you will think otherwise.
