A Vehicle Tracking System using the C programming language is a system designed to monitor and track the real-time or simulated location of vehicles. Since C is a low-level language that interacts closely with hardware, this system is often built for embedded systems, such as GPS modules, microcontrollers (e.g., Arduino), or simple desktop simulations.

The system can log vehicle coordinates, calculate speed, and store the route information in memory or files. It’s commonly used in logistics, fleet management, and personal vehicle tracking.

???? Key Features

????️ GPS Data Simulation or Integration:

Either integrate actual GPS hardware or simulate GPS coordinates in C.

???? Location Tracking:

Track and update vehicle coordinates at regular intervals.

???? Speed & Distance Calculation:

Calculate vehicle speed using position and time data.

???? Data Logging:

Store tracking data in a file for later analysis.

???? Simple Interface (Console-based):

View current location, speed, total distance on the console.

⚙️ How It Works

GPS Module / Simulation:

For embedded applications, a GPS module sends location data via serial port (UART).

For simulation, coordinates are hardcoded or generated randomly in C.

Data Parsing:

If using actual GPS, C reads and parses NMEA sentences (like $GPGGA, $GPRMC).

Processing & Display:

The coordinates are displayed on screen.

Speed and distance between two points are calculated using Haversine formula.

Data Logging:

All movement data is logged into a .txt or .csv file using standard file I/O.

????️ Technologies/Tools Used

✅ Advantages
