Many devices report via standardized NMEA sentences. The tracking portal supports generic parsing of the positions sentences, including GPRMC, GPGGA, GPGLL, GPGSV, GPVTG and GPGSA.

However, NMEA submissions must have an identifying sentence prefixed in order to correctly identify the submitting device. The prefixed message should be formatted as such:

$GPSTN,{UniqueId},{DeviceType},{Model}

{DeviceType} and {Model} are optional.

An example NMEA submission is thus (1234567890 being the unique identifier):
  • $GPSTN,1234567890
  • $GPRMC,160700.000,A,3855.6524,N,07712.9790,W,0.00,191.38,170316,,,A*76
  • $GPGSA,A,3,32,14,31,10,22,18,01,11,,,,,2.2,1.6,1.5*3E
  • $GPGGA,160701.000,3855.6524,N,07712.9790,W,1,08,1.6,125.1,M,-33.5,M,,0000*65
  • $GPGSV,3,3,12,25,45,090,,12,25,051,,04,22,281,,26,02,188,*7D
