The LH90 Tethered UAV is an advanced unmanned aerial system designed for persistent surveillance, reconnaissance, and communication relay missions. Unlike conventional drones that rely on onboard batteries, the LH90 operates via a tethered power supply, enabling extended flight durations limited only by the tether's length and power source. This unique feature makes it ideal for applications requiring continuous aerial coverage, such as border security, event monitoring, and infrastructure inspection. Key Features 1. Unlimited Flight Time – The LH90 is powered through a lightweight, high-strength tether connected to a ground-based power supply, eliminating the need for battery swaps or recharging. This allows for uninterrupted operation over extended periods, far exceeding the endurance of battery-powered UAVs. 2. Stable and Reliable Performance – The tether not only provides power but also ensures a secure data link, reducing vulnerability to signal interference or jamming. The LH90 maintains a stable hover even in challenging weather conditions, thanks to its advanced flight control system and aerodynamic design. 3. High-Resolution Payload Options – The UAV can be equipped with various payloads, including high-definition EO/IR (electro-optical/infrared) cameras, multispectral sensors, or communication relays. This versatility makes it suitable for day-and-night surveillance, search and rescue, and disaster response operations. 4. Rapid Deployment – The system is designed for quick setup, with automated takeoff and landing capabilities. Operators can deploy the LH90 within minutes, making it an efficient solution for emergency situations or temporary security needs. 5. Enhanced Safety and Compliance – Since the UAV remains tethered, it operates within a confined airspace, minimizing risks of mid-air collisions or fly-away incidents. This feature also simplifies regulatory compliance in restricted or urban environments. Applications - Security & Defense – Persistent surveillance for military bases, critical infrastructure, and public events. - Disaster Response – Real-time situational awareness during floods, earthquakes, or wildfires. - Telecommunications – Temporary communication relay for emergency networks or remote areas. - Industrial Inspections – Monitoring pipelines, power lines, and construction sites without downtime. Conclusion The LH90 Tethered UAV combines endurance, stability, and adaptability, making it a powerful tool for missions requiring long-duration aerial presence. Its tether-based operation ensures reliability, while its modular payload system allows customization for diverse operational needs. Whether for defense, public safety, or industrial applications, the LH90 provides a cost-effective and efficient alternative to traditional drones and manned aircraft.
