GPSReader

GPSReader is a C# library designed to parse NMEA 0183 sentences from GPS devices. It provides a flexible and extensible way to handle different types of NMEA sentences.

Features

• Supports reading NMEA sentences from a serial port(real-time) or a file(simulation purpose).
• Supports multiple NMEA sentence types (GPGGA, GPGSA, GPGLL, GPGSV).
• Event-driven architecture allows for real-time processing of GPS data.
• Customizable parser list allows for easy addition of new sentence types.

Hardware Requirements

Any GPS device that outputs NMEA 0183 sentences over a serial port should work with GPSReader. You can also use a file containing NMEA sentences for testing purposes. I bought a GPS module VK-162 and connected it to my computer. You can find it on Amazon or AliExpress.

Usage

To use GPSReader, you need to create an instance of GPSReaderService, passing in an ILogger, an INMEAInput, and a list of BaseNMEAParser objects.

var parsers = new List<BaseNMEAParser>
{
    new GPGGAParser(),
    new GPGSAParser(),
    // Add or remove parsers as needed
};

var gpsReaderService = new GPSReaderService(logger, input, parsers);

You can then subscribe to the events provided by GPSReaderService to handle the parsed data.

gpsReaderService.OnGPGGAUpdated += (sender, args) =>
{
    // Handle GPGGA data
};

gpsReaderService.OnGPGSAUpdated += (sender, args) =>
{
    // Handle GPGSA data
};

// Subscribe to other events as needed

Example

You can find an example of how to use GPSReader in the ConsoleApp project under example folder. This project contains a simple console application that reads GPS data from a file and prints the parsed data to the console.
