- UPDATE mTxtAltitude, mTxtHacc and mTxtVacc because GNSS receivers can output higher accuracy! (RTK) According to https://www.gpsinformation.org/dale/nmea.htm#GGA I suggest an update to the quality information for the GGA sentence. Since RTK solutions become more and more standard the info.quality "Fix RTK" is a very important information!
