6. GPS/GLONASS and BeiDou Switching 11 It is the data of GPS/GLONASS protocol outputting from the module by default. You can modify to the BeiDou protocol though the testing software. The steps are shown in the following figures. Select NMEA(NMEA Protocol) and set the NEMA Version to 4.1, and then click [Send] to save this modification.
The $GB indicates that the data meets BeiDou protocol. 12
13 7. Longitude and Latitude Switching $GPRMC,060556.00,A,2236.91418,N,11403.24669,E,0.034,,130214,,,D*7F Input the results in Google Earth and search, you can get the detailed position information.
14 8. Protocols for Setting U-blox Parameters You can send commands through serial port to modify the settings. The HEX must be selected when you send commands through the serial port of PC software. It will cost 300ms to start the U-blox for the first time.
