This study presents the development of a lightweight unmanned aerial vehicle (UAV) system optimized for high-precision image acquisition and real-time data processing. To enhance mobility and field operability, the UAV was miniaturized and integrated with a mission computer, camera control systems, and LTE-based communication modules within a compact form factor. The design includes a lightweight frame, embedded flight controller, and integrated power board to reduce total weight while maintaining flight stability and endurance. The system was validated through field tests, achieving a maximum flight time of 30 minutes with a fully integrated payload under 5.4 kg. This lightweight UAV platform enables efficient deployment in land surveying, disaster monitoring, and reconnaissance missions, particularly in areas requiring rapid response. The results contribute to the advancement of compact UAV technologies and strengthen the practical applicability of domestic drone systems in both civilian and governmental sectors.
