NMEA-GPGGA-Data-Processor

NMEA GPGGA Data Processor

This project is a C++ application designed to read and process NMEA GPGGA sentences from a text file. The program extracts key information such as time, latitude, longitude, and the number of satellites from each GPGGA sentence and displays it in a readable format.

Features

• Parses NMEA GPGGA sentences.
• Extracts and formats the time, latitude, longitude, and satellite count.
• Reads from a specified text file containing NMEA messages.
• Handles various edge cases and invalid data gracefully.
• Outputs the extracted data in a human-readable format.

Getting Started

Prerequisites

• A C++11 compatible compiler (e.g., g++, clang++)
• Basic knowledge of command-line operations

Installation

1. Clone the repository:

    git clone https://github.com/yourusername/nmea-gpgga-processor.git
    cd nmea-gpgga-processor
   

2. Prepare your data:
   • Ensure you have a text file (e.g., nmea_messages.txt) containing NMEA GPGGA sentences.
   • Place this file in the same directory as the source code.

Usage

Compilation

To compile the program, use the following command:

g++ -o gpgga_processor main.cpp

Execution

To run the executable, use the following command:

./gpgga_processor

Ensure that the nmea_messages.txt file is in the same directory as the executable or specify the full path to the file in the source code.

Example Output

When you run the program, you will see output similar to the following if the input file contains valid GPGGA sentences:

Time: 12:34:56, Latitude: 4807.038 N, Longitude: 01131.000 E, Satellite Count: 8
Time: 12:35:01, Latitude: 4807.123 N, Longitude: 01131.456 E, Satellite Count: 10

Code Overview

The main components of the project are:

• GPGGAData struct: A structure to hold the parsed GPGGA data fields.
• process_gpgga_line function: Parses a single GPGGA line and populates a GPGGAData object.
• read_and_process_file function: Reads the file line by line, processes each GPGGA line, and stores the results.
• main function: The entry point of the application, which handles file reading and data output.

Error Handling

• The program checks if the file can be opened successfully.
• It verifies that each line contains a valid GPGGA sentence before attempting to parse it.
• If an error occurs during parsing, the program skips the invalid line and continues processing the next line.

Dependencies

• C++11 or later
