*GPS_NMEA(0) .GPSb. 0 l - 64 377 0.000 17.842
PPS(0) .PPSb. 0 l - 16 0 0.000 0.000
You could be doing much better if you got the PPS working as well. Note
that the reach is zero. The PPS line should have a "o" as the first
character if it's working properly (like the NMEA has a "*").
Perhaps you need to rebuild the kernel with PPS support - but I'm not
familiar enough with Linux to know whether that's required. Perhaps
someone can help with your Debian OS (Version 2.6.26.pps001).
