At the moment there is no problem when using GPS only devices, NMEA string with information about speed, DOP value etc starts with GP.. prefix. But with Glonass included NMEA string has different prefix GN.. and information about DOP and speed are not recognized in Qgis. Is it planned to update this also? Position is ok, in both cases. regards, radek
