[gpsd-dev] GNGNS unknown sentence with ublox

[Max Schulze]

Hello,

I am using gpsd with an u-blox EVN-M8N (evaluation kit) and I noticed
that gpsd has some trouble interpreting a message type. However, this
multi-gnss message seems rather standard and should be supported.

gpsd:WARN: unknown sentence:
"$GNGNS,120040.00,5033.12853,N,00854.62178,E,DN,10,0.91,120.3,46.5,,0000*64\x0d\x0a"

(note, the checksum might not be correct anymore. I modified the UTC,
Lat, Lon)

If you advise, maybe I can generate better debug logs for additional
troubleshooting?
