ASTRA-Anti-Spoofing Tracking and Remote Access System 
The ASTRA system is a resilient vehicle tracking solution designed for GPS-compromised 
environments. By integrating an ESP32, SIM7600 LTE/GNSS module, and MPU9250 IMU, the 
system employs sensor fusion and dead reckoning to maintain coordinate accuracy during signal 
manipulation. It further enhances reliability by utilizing Google Maps(Geolocation API} for cellular 
trilateration when GNSS is unavailable. 
The prototype autonomously detects spoofing attacks and switches to backup positioning 
mechanisms, ensuring continuous tracking. Data is securely transmitted via a Node.js backend, 
NGROK, and HiveMQ (MQTT) to a real-time HTML dashboard, providing uninterrupted situational 
awareness and robust tracking integrity through a scalable, encrypted architecture. 
By combining embedded systems, wireless communication, sensor fusion, cellular trilateration, and 
secure cloud-based telemetry, ASTRA presents a scalable and future-ready solution for resilient vehicle tracking.
