Reliable location tracking in remote and infrastructure-deficient areas remains a significant challenge, especially where cellular or Wi-Fi networks are sparse or unavailable. Traditional tracking systems often rely on short-range communication or high-cost GSM modules, making them unsuitable for rural applications. This project investigates the potential of combining GPS geolocation with LoRa-based communication to create a low-cost, energy-efficient tracking solution that performs effectively in long-range, low-power scenarios. An evaluation of existing tracking technologies revealed critical limitations in affordability, coverage, and power consumption, particularly for portable and field-based use cases. These findings led to the design and development of a lightweight tracker device that leverages low-power wide-area networking (LPWAN) for data transmission. The system is built around the Arduino UNO microcontroller, integrated with a NEO-6M GPS module for real-time coordinate acquisition and an SX1278 LoRa transceiver for wireless communication. A custom-designed PCB was implemented to streamline the hardware and reduce the footprint of the device. The tracker periodically captures GPS data and transmits it via LoRa to a remote receiver, enabling live monitoring without dependency on cellular infrastructure. Field deployment tests demonstrated successful real-time tracking with reliable transmission over distances up to 2 kilometers, maintaining low packet loss and minimal power draw throughout operation.This LoRa-GPS tracker provides a scalable and adaptable alternative for various use cases, including livestock monitoring, luggage tracking, and search-and-rescue support in disconnected terrains. Unlike conventional GSM-based systems, the proposed solution offers superior range, reduced operational costs, and a modular design suitable for expansion. Future enhancements include replacing the Arduino UNO with more power-efficient microcontrollers, implementing encryption for secure data transfer, and extending communication range through mesh networking.
