Live Location Tracking System: Architecture, Algorithms, and Real-Time Visualization

Abstract: Live location tracking systems have revolutionized modern logistics, emergency response, and personal safety applications. These systems facilitate the continuous acquisition, transmission, processing, and visualization of geographical position data in near real-time. This comprehensive research paper presents a robust and scalable architecture for a live location tracking system. The architecture integrates a mobile client for GNSS/GPS coordinate acquisition, an optimized communication layer using lightweight protocols like MQTT and WebSockets, a robust backend for spatial data processing, and a dynamic webbased dashboard for visualization. Furthermore, this study delves deeply into the underlying algorithms, including Kalman Filtering for coordinate smoothing and the Haversine formula for distance calculation. Security and privacy, paramount in location-based services, are addressed through strict role-based access control and TLS 1.3 encryption. Extensive experimental evaluation demonstrates that the proposed architecture minimizes end-to-end latency while maintaining high accuracy and low battery consumption. The findings provide a foundational framework for deploying enterprise-grade location tracking solutions.
