Design and Development of an IoT-Enabled Long-Range Surveillance Hexacopter UAV with GPS Tracking and Real-Time Video Transmission

Abstract

Unmanned Aerial Vehicles (UAVs) have gained significant importance in surveillance and monitoring applications due to their flexibility, mobility, and ability to access remote or hazardous locations. This paper presents the design and development of a long-range surveillance hexacopter drone integrated with GPS tracking, telemetry communication, and real-time video transmission capabilities. The proposed system employs a six-rotor configuration powered by brushless DC motors and controlled through a flight controller to ensure stable flight performance and enhanced payload carrying capability. A GPS module is incorporated to provide accurate location tracking, while a wireless telemetry system enables continuous communication between the drone and the ground control station. An onboard camera captures and transmits live video streams for real-time surveillance and monitoring purposes. The developed UAV platform was evaluated for flight stability, communication range, tracking performance, and surveillance effectiveness. Experimental observations indicate reliable operation, stable flight characteristics, and effective real-time monitoring over extended distances. The proposed surveillance drone offers a cost-effective and efficient solution for applications such as border security, disaster management, traffic monitoring, environmental observation, infrastructure inspection, and search-and-rescue operations. The results demonstrate that the developed hexacopter UAV can successfully perform aerial surveillance tasks while maintaining operational reliability and communication efficiency.

Introduction

This paper presents the design and development of a long-range surveillance hexacopter drone for real-time monitoring, location tracking, and aerial surveillance applications. UAVs have become increasingly important in security, disaster management, infrastructure inspection, environmental monitoring, and search-and-rescue operations because they provide flexible, cost-effective, and wide-area coverage compared to traditional surveillance systems.

The proposed drone uses a hexacopter configuration, which offers greater stability, higher payload capacity, and improved reliability than conventional quadcopters. The system integrates brushless DC motors, electronic speed controllers (ESCs), a KK2.1.5 flight controller, GPS module, telemetry communication system, onboard camera, and Li-Po battery to achieve stable flight and efficient surveillance performance.

The drone architecture consists of four main subsystems:

• Propulsion System: Six brushless DC motors controlled by ESCs generate thrust and enable roll, pitch, yaw, and altitude control.
• Flight Control System: The KK2.1.5 controller stabilizes the UAV using sensor feedback and continuously adjusts motor speeds.
• GPS Tracking System: Provides real-time location information and improves navigation accuracy and operational safety.
• Telemetry and Surveillance System: Enables wireless transmission of flight data and live video streaming to the ground station for remote monitoring.

The operational process begins with GPS initialization and communication setup. During flight, the controller processes pilot commands, maintains stability, transmits telemetry data, and streams live video from the onboard camera, allowing operators to monitor target areas remotely.

Experimental testing demonstrated that the developed hexacopter achieved stable takeoff, hovering, maneuvering, and landing performance. The communication system operating at 2.4 GHz maintained reliable connectivity up to approximately 1 km, while the GPS module successfully provided continuous real-time location tracking. The onboard camera delivered effective live video transmission for surveillance purposes.

Key performance results include:

• Hexacopter configuration
• Maximum thrust: 3 kg
• Payload capacity: 1 kg
• Communication range: ~1 km
• Successful GPS tracking
• Successful live video streaming
• Stable flight performance
• Effective surveillance capability

Overall, the study concludes that the developed long-range surveillance hexacopter successfully integrates flight control, GPS navigation, telemetry communication, and real-time video transmission into a single platform. The system offers improved mobility, wider coverage, lower operational costs, and effective monitoring capabilities, making it suitable for security surveillance, disaster response, infrastructure inspection, and environmental observation applications.

Conclusion

A long-range surveillance hexacopter UAV was successfully designed and developed for real-time monitoring and tracking applications. The proposed system integrates a hexacopter platform with a flight controller, GPS tracking module, telemetry communication system, and onboard camera to provide reliable surveillance capabilities. The six-rotor configuration offered enhanced flight stability, improved payload carrying capacity, and better operational reliability compared to conventional multirotor platforms. The implemented GPS module enabled accurate location tracking, while the telemetry system ensured continuous communication between the UAV and the ground station. Real-time video transmission provided effective monitoring of remote locations, making the system suitable for surveillance and reconnaissance operations. Experimental observations demonstrated stable flight performance, reliable communication over a range of approximately 1 km, and successful real-time monitoring capabilities. The developed surveillance drone provides a cost-effective and flexible solution for applications such as border security, disaster management, traffic monitoring, environmental observation, infrastructure inspection, and search-and-rescue missions. The results indicate that the proposed hexacopter platform can effectively perform aerial surveillance tasks while maintaining operational efficiency and system reliability. Future enhancements may include autonomous navigation, artificial intelligence-based object detection, obstacle avoidance systems, thermal imaging cameras, and extended communication capabilities to further improve the performance and versatility of the surveillance platform.
