Understanding NMEA 0183 Sentences: The Language of Marine Electronics
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 nmea 0183 sentences
There are dozens of standardized sentence types, but a few are ubiquitous in GPS and navigation projects: Understanding NMEA 0183 Sentences: The Language of Marine
The National Marine Electronics Association (NMEA) developed the 0183 standard to allow multiple devices to share data over a simple serial interface. Unlike its successor NMEA 2000 (a CAN-based system), NMEA 0183 is (RS-232, RS-422, or TTL levels) with a talker-listener architecture: only one device (talker) can transmit on a line at a time, but multiple listeners can receive the same data stream. A sentence is limited to a maximum of
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
