This project is a comprehensive GPS solution developed for BeagleBone Black/Green. It provides a full suite of location-based services, from raw NMEA data parsing to advanced navigation math and remote SMS reporting using SIM808/GSM modules.

The system is divided into three main functional modules:

1. Core Tracking: Real-time extraction of decimal coordinates, altitude, and synchronized local time from satellite data.
2. Smart Navigation: Implementation of the Haversine Formula to calculate the distance (meters) and bearing (compass direction) to any target destination.
3. SMS Integration: A remote reporting system that sends current location, time, and status to a mobile phone via AT commands.

• Microcontroller: BeagleBone Black / Green.
• GPS/GSM Module: SIM808 or equivalent (connected via UART).
• BeagleBone Pins:
  • TX: P9_24 (UART1_TXD)
  • RX: P9_26 (UART1_RXD)
• Baud Rates: 9600 (GPS) / 115200 (Modem).

Install the required Python library:

pip install pyserial
Running the Modules
For basic tracking: python GPS_Core.py

For navigation to a target: python GPS_Navigation.py

For sending location via SMS: python GPS_SMS_Alert.py

⚙️ Features & Logic
Local Time Sync: Automatically adjusts UTC satellite time to your local timezone (e.g., UTC+3).

Automatic Pin Muxing: Uses config-pin to ensure UART is ready on boot.

Fail-safe SMS: Includes a SIM PIN check and prompt detection (>) for reliable messaging.

Navigation Accuracy: Uses spherical trigonometry for precise azimuth (Bearing) calculations.
