I read the GPS NMEA data directly from /dev/serial0 from our first IMU-3 device I get
$GNGGA instead of $GPGGA
$GNRMC instaed of $GPRMC
$GNGSA instaed of $GPGSA
the values are O.K.
I'm working only with this 3 records, but there are many other $GNxxx Records.
will the new GPS receiver receive from all 4 satellite systems, if so, do I correctly read the Glonass statistics from $GLGSV ? And GPS + Galileo output their statistics together in $GPGSV? While the localization data from all systems is sent in $GNGGA and $GNRMC?
But no matter if my assignment is correct, with your 'old' receiver I get 10-12 satellites and now with the new 24-26. Congratulations !!!!
