# uBlox GPS Module Reader
This repository contains a simple C# application that reads GPS data from a uBlox GPS module via a serial port. It processes the GPS NMEA sentences, particularly `$GPGGA` and `$GPRMC`, and converts the raw latitude and longitude values into decimal degrees.
## Requirements
- .NET Framework SDK
- A uBlox GPS module connected via a serial port (e.g., COM5)
- A serial-to-USB adapter (if using a USB GPS device)
## Application Logic
- The application attempts to connect to the GPS module via the serial port.
- It listens for GPS data on the specified serial port.
- The GPS data (NMEA sentences) is parsed, and the latitude and longitude values are extracted from `$GPGGA` and `$GPRMC` sentences.
- The raw coordinates are converted from the `DDMM.MMMM` format to decimal degrees and displayed on the console.
## Code Walkthrough
1. **Serial Port Configuration**:
The application uses the `System.IO.Ports.SerialPort` class to communicate with the GPS module. You need to specify the correct port name (e.g., COM5), baud rate, stop bits, parity, and handshake for the connection.
2. **Data Reception**:
When data is received from the GPS module, the `GpsModuleOnDataReceived` event handler is triggered. It reads the data from the serial port, splits it by newline characters, and checks for the `$GPGGA` and `$GPRMC` sentences.
3. **Coordinate Conversion**:
The `ConvertToDecimalDegrees` method is used to convert the raw latitude and longitude values (in the `DDMM.MMMM` format) into decimal degrees.
4. **Output**:
The coordinates are printed on the console in the following format:
```
yyyy-MM-ddTHH:mm:ss => latitude, longitude
```
## Example Output
```bash
2025-01-06T12:30:45 => 37.774929, -122.419418
```
## Notes
- The `Thread.Sleep(300)` is added to throttle the data processing slightly. You can adjust or remove this delay depending on the performance requirements.
- Make sure that the GPS module is powered on and outputting NMEA sentences.
- The program works best with a direct connection to the GPS module. If using a USB-to-serial adapter, ensure the correct COM port is specified.
