1. Core Specifications
Purpose: Data exchange between GPS receivers, sensors, and marine/aviation/vehicle systems
Latest Version: 4.11 (though v3.01 remains widely adopted)
Key Features:
ASCII-based text format
Master-slave architecture (1 Talker → Multiple Listeners)
Default settings: 4800 baud, 8 data bits, no parity, 1 stop bit
2. Essential Data Sentences
Each sentence starts with $ followed by a 5-character identifier:
| Sentence | Description | Example (Simplified) |
| $GPGGA | Global Positioning Data | $GPGGA,092725.00,4717.11399,N,00833.91590,E,1,08,1.01,499.6,M,48.0,M,,*5B |
| $GPRMC | Recommended Minimum Data | $GPRMC,092725.00,A,4717.11399,N,00833.91590,E,0.004,77.52,091202,,,A*57 |
| $GPGSV | Satellite View | $GPGSV,3,1,11,03,03,111,00,04,15,270,00,06,01,010,00,13,06,292,00*74 |
| $GPVTG | Track & Speed Over Ground | $GPVTG,77.52,T,,M,0.004,N,0.008,K,A*06 |
3. Data Format Decoding ($GPRMC Example)
$GPRMC,<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>,<10>,<11>,<12>*<checksum>
| Field | Meaning | Sample Value |
| 1 | UTC Time (HHMMSS.SS) | 092725.00 |
| 2 | Status (A=Valid, V=Invalid) | A |
| 3 | Latitude (DDMM.MMMMM) | 4717.11399 |
| 4 | Latitude Hemisphere (N/S) | N |
| 5 | Longitude (DDDMM.MMMMM) | 00833.91590 |
| 6 | Longitude Hemisphere (E/W) | E |
| 7 | Speed Over Ground (knots) | 0.004 |
| 8 | Course Over Ground (deg) | 77.52 |
| 9 | UTC Date (DDMMYY) | 091202 |
| 10 | Magnetic Variation (deg) | (null) |
| 11 | Variation Direction (E/W) | (null) |
| 12 | Mode Indicator (A=Autonomous) | A |
4. Practical Applications
Vehicle Navigation: Parse $GPRMC for real-time position/speed
Marine Tracking: Combine GPGGA(altitude)+GPGGA(altitude)+GPGSV (satellites)
Drone Control: Use $GPVTG for yaw calculation
Data Logging: Store raw NMEA sentences for analysis
5. Limitations
Low Bandwidth: Typically 1Hz update rate
No Encryption: Plaintext transmission
Poor Extensibility: Custom sentences required for new sensors (e.g., $PSTI)
