Global Positioning System Fix Data (GGA) GPS positioning information

　　$GPGGA,<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>,M,<10>,M,<11> ,<12>*hh

　　<1> UTC time, hhmmss (hours, minutes, seconds) format

　　<2> Latitude ddmm.mmmm (degree minutes) format (the leading 0 will also be transmitted)

　　<3> Latitude hemisphere N (northern hemisphere) or S (southern hemisphere)

　　<4> Longitude dddmm.mmmm (degree minutes) format (the leading 0 will also be transmitted)

　　<5> Longitude Hemisphere E (East Longitude) or W (West Longitude)

　　<6> GPS status: 0=not positioned, 1=non-differential positioned, 2=differential positioned, 6=estimated

　　<7> The number of satellites (00~12) that are using the solved position (the preceding 0 will also be transmitted)

　　<8> HDOP level precision factor (0.5~99.9)

　　<9> Altitude (-9999.9~99999.9)

　　<10> The height of the earth's ellipsoid relative to the geoid

　　<11> Differential time (the number of seconds since the last received differential signal, if it is not differential positioning, it will be empty)

　　<12> Differential station ID number 0000~1023 (the previous 0 will also be transmitted, if it is not differential positioning, it will be empty)
