In this example:
!AIVDM,1,1,,A,14eG;`@001EqH4`S0kH4pD3pGv2222220,0*3E
Every NMEA 0183 sentence follows a strict structural format to ensure it can be correctly parsed by "listeners" (receiving devices) from a "talker" (transmitting device). A sentence is limited to a maximum of and consists of the following components: NMEA 0183 - National Marine Electronics Association nmea 0183 sentences
Every valid NMEA sentence follows a specific structure. Let’s break down the example above:
Here's an example of a $GPGGA sentence:
$SDDPT,12.5,0.0,5.0*7D
A sentence typically looks like this: $GPGGA,123519,4807.038,N,01131.000,E,1,08,0.9,545.4,M,46.9,M,,*47 In this example:
$TTSSS,data1,data2,...,dataN*HH<CR><LF>
