Product Parameters:

NMEA 0183 Protocol Overview

A standardized serial data communication protocol developed by the National Marine Electronics Association (NMEA), primarily used for GPS and navigation systems.

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:

3. Data Format Decoding ($GPRMC Example)

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

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)
