Executive Summary

The Jolt Locator is a GPS-based autonomous navigation device designed to provide real-time directional guidance to predefined destinations without requiring internet connectivity. This project demonstrates a fully functional prototype that addresses real-world challenges in offline navigation, emergency wayfinding, and GPS-denied environment transitions. The system combines GPS positioning with digital compass technology and an intuitive LED-based feedback system, making it suitable for applications in outdoor recreation, emergency preparedness, agricultural field mapping, and educational demonstrations of GPS technology.

Key Project Achievements

• 4 integrated sensors/modules with multi-protocol communication (UART, I2C, GPIO)
• Real-time OLED display showing coordinates, distance, bearing, and navigation status
• RGB LED navigation system with color-coded directional feedback
• Haversine formula implementation for accurate distance calculation
• Compass-based bearing guidance with ±2° heading accuracy
• Complete offline operation requiring no internet connectivity
• 20-meter arrival detection for destination confirmation
