3.28.1.7. AT$GNSSCONST - GNSS constellations configuration
This command handles the configuration of the constellations to be used for the
solution.
The <mask> value defines which
constellations will be used for the solution.
The default value is 1F (all enabled). GPS and
QZSS constellation are always active and bit
0 and 4 must always be set to 1. However,
keep in mind that, although QZSS is used as
augmentation to other GNSS systems, the
device does not provide NMEA data.
