Recommended Minimum Specific GPS/TRANSIT Data (RMC) GPS recommended positioning information

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

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

　　<2> Positioning status, A=valid positioning, V=invalid positioning

　　<3> Latitude ddmm.mmmm (degree minutes) format (the leading 0 will also be transmitted)

　　<4> Latitude hemisphere N (northern hemisphere) or S (southern hemisphere)

　　<5> Longitude dddmm.mmmm (degree minutes) format (the leading 0 will also be transmitted)

　　<6> Longitude Hemisphere E (East Longitude) or W (West Longitude)

　　<7> Ground rate (000.0~999.9 section, the preceding 0 will also be transmitted)

　　<8> Ground heading (000.0~359.9 degrees, based on true north, the preceding 0 will also be transmitted)

　　<9> UTC date in ddmmyy (ddmmyy) format

　　<10> Magnetic declination (000.0~180.0 degrees, the previous 0 will also be transmitted)

　　<11> Magnetic declination direction, E (East) or W (West)

　　<12> Mode indication (only NMEA0183 version 3.00 output, A=autonomous positioning, D=differential, E=estimated, N=invalid data)

　　Track Made Good and Ground Speed (VTG) GPS ground speed information

　　$GPVTG,<1>,T,<2>,M,<3>,N,<4>,K,<5>*hh

　　<1> Ground heading with reference to true north (000~359 degrees, the preceding 0 will also be transmitted)

　　<2> Ground heading with reference to magnetic north (000~359 degrees, the preceding 0 will also be transmitted)

　　<3> Ground rate (000.0~999.9 section, the preceding 0 will also be transmitted)

　　<4> Ground speed (0000.0~1851.8 km/h, the preceding 0 will also be transmitted)

　　<5> Mode indication (NMEA only0183 3.00 version output, A=autonomous positioning, D=differential, E=estimated, N=data invalid)
