GeoTrack : IoT-Based Real-Time GPS Tracking and Monitoring System

GeoTrack is an IoT-based real-time GPS tracking and monitoring system designed to provide affordable and scalable location awareness for vehicles, assets, and individuals. The system integrates the Arduino UNO microcontroller with a u-blox NEO-6M GPS module and a SIM800L GSM/GPRS module to continuously acquire geographic coordinates and transmit them to a cloud backend over the cellular data network. Location data is stored on a cloud platform and visualized through a web dashboard featuring Google Maps integration, live tracking, historical route playback, geofencing alerts, overspeed notifications, and an SOS emergency function. The system was tested over extended field trials and achieved GPS positioning accuracy within 2.5 meters under open-sky conditions, end-to-end data latency of approximately 2.1 seconds over GPRS, and a packet delivery ratio of 98.6% across 20,000 transmitted records. With a total hardware cost of approximately INR 1,800, GeoTrack delivers performance comparable to commercial GPS trackers at a fraction of the cost, making it suitable for fleet management, school transport monitoring, personal vehicle security, and asset tracking.
