The value of tmnxGnssConstellation specifies the type of satellites that the GNSS receiver will use to acquire a fix. The value 'gps' specifies that the receiver will only use the United States' Global Positioning System (GPS) satellites. The value 'gps-glonass' specifies that the receiver will use both GPS and Russia's GLONASS satellites. Changing the satellite constellation requires the MDA to be reset. The MDA will reset automatically when GNSS is enabled after changing the constellation.
