  • Case Study: Tethered Drone Night Lighting — Kitefly × Geely Radar
    04-07 2026
    Published by Kitefly Tethered | www.tetheredsystem.com The Challenge: Powering Aerial Lighting Without Fixed Infrastructure Night operations in emergency rescue, power grid repair, and remote construction sites share a common problem: no reliable power source, no adequate ground lighting, and no flexible solution. Traditional lighting towers are fixed. Generators are heavy and noisy. Ground-mounted floodlights can't reach overhead blind spots. This case study documents a joint field test between Kitefly Tethered, Geely Radar , and DJI — validating a fully mobile, high-power aerial lighting system that eliminates dependence on grid power or stationary equipment. System Overview: Three Integrated Modules The tested configuration combines three purpose-matched components into a single deployable unit. Module 1 — Mobile Power Source: Geely Radar Vehicle Discharge System The Geely Radar pickup truck features a vehicle-grade bidirectional power export system capable of delivering stable 220V AC output. This matches directly with the Kitefly G7 tethered ground station, which has a maximum power draw of 7,000W. Key advantage: The vehicle functions as a mobile power station. Drive it to site — power is immediately available. No grid connection. No generator setup. This is particularly critical for: · Disaster zones with no utility infrastructure · Remote road sections and construction corridors · Rapid-deployment emergency scenarios Module 2 — Tethered Power Core: Kitefly AF-G7 M400 Tethered System The Kitefly AF-G7 is engineered specifically for the DJI M400 platform. It serves as the power bridge between the ground station and the airborne drone. Technical specifications: Parameter Value Input voltage AC 220V Max ground station output 7,000W Airborne module output Max 3,000W Airborne module weight < 1 kg Max cable retrieval speed ≥ 2 m/s Cable management Passive payout / Active retrieval Airborne module material Aviation-grade aluminum alloy Protection features Overvoltage, undervoltage, over-temperature, short circuit The airborne power module converts high-voltage DC from the tether cable to low-voltage DC for the drone and payload. Its sub-1kg weight adds minimal load to the M400 airframe. At approximately 5 meters altitude during descent, the system automatically cuts high-voltage output — a built-in safety protocol that requires no manual intervention. Module 3 — Aerial Platform and Lighting Payload: DJI M400 + Kitefly High-Power Lighting Module DJI M400 platform highlights: · IP55 weather resistance — operational in rain, dust, and harsh conditions · RTK precision hovering: ±0.1m positional accuracy · Omnidirectional obstacle avoidance: dual visual sensors + LiDAR The Kitefly High-Power Aerial Lighting Module is the core illumination payload: Parameter Value Maximum power 3,000W Luminous flux (3,000W mode) > 440,000 lm Effective illumination area Up to 20,000 m² Light source COB (Chip-on-Board) array Dimming control 3-stage remote adjustment Remote switch Yes — wireless handheld control Mounting CNC quick-release bracket Thermal management Auto power reduction on overtemperature At 3,000W with 440,000+ lumens, this module delivers illumination comparable to a professional stadium lighting setup — from a drone hovering at 50 meters. Field Test: Step-by-Step Operation The complete system was assembled and operated without specialized tools or complex calibration. Step 1 — AssemblyMount the airborne power module and interface board onto the DJI M400 using quick-release rails. Confirm seating with an audible click. Attach the lighting module to the landing gear via quick-release screws. Connect the power interface. No tools required. Step 2 — Power ConnectionActivate the Geely Radar vehicle discharge function. Connect the Kitefly G7 ground station to the 220V vehicle output. Connect the tether cable to the drone's airborne module. Secure cable to landing gear as the mechanical strain relief point. Step 3 — Takeoff and LightingPower on the remote controller and unlock the drone. The M400 lifts off smoothly. Activate high-voltage output from the ground station — the lighting module illuminates instantly at full brightness. All light control (on/off, 3-stage power, brightness) is operated via the remote controller: short press to activate, sequential presses to cycle power levels, long press to shut off. Step 4 — Stable OperationDuring the test, the M400 maintained precision hover at 50 meters altitude. At 3,000W output, the lighting covered the entire test site. Ground-level detail was clearly visible. No voltage fluctuation was recorded throughout the test duration. Step 5 — Safe LandingUpon test completion, the ground station automatically engaged cable retrieval mode. As the drone descended to approximately 5 meters, high-voltage output was automatically cut. The drone completed its final approach under manual RC control. No safety incidents recorded. Validated Use Cases This system configuration is applicable across four high-demand sectors: Emergency Rescue In earthquake or flood scenarios where grid power is unavailable, the Geely Radar vehicle reaches the site and provides immediate power. The tethered drone climbs to altitude within minutes. At 440,000+ lumens over 20,000m², search teams gain full-area illumination. Combined with the M400's thermal imaging capability, rescue teams reduce blind spots during the critical early response window. Power Grid Maintenance For line repairs crossing highways, railways, or terrain obstacles, ground lighting is often obstructed or insufficient. This system provides targeted overhead illumination with 12+ hours of continuous operation — sufficient to cover an entire repair shift without interruption. Infrastructure and Construction Remote road construction and night-shift engineering sites benefit from the system's mobility. As the work zone moves, the vehicle moves with it. The 20,000m² coverage area accommodates large active construction zones in a single deployment. Public Safety and Events For large-scale outdoor events or nighttime security operations, a tethered drone provides elevated, wide-angle illumination that eliminates shadows and coverage gaps. The strobe function can serve as an active visual alert in incident scenarios. Why This Combination Works Three separate technologies were integrated in this test. Each solves a specific constraint that the others cannot: · Geely Radar eliminates the need for grid access or heavy generators — it brings the power source to the operation. · Kitefly AF-G7 eliminates the battery endurance limit — the drone operates continuously as long as vehicle power is available. · DJI M400 + Kitefly Lighting Module eliminates ground-level coverage limitations — illumination is delivered from altitude, at scale. The combination is deployable within minutes, operable by a small team, and applicable to environments where fixed infrastructure does not exist.

Why This Project Matters High-rise glass curtain wall cleaning has long relied on rope-suspended workers - a method that is slow, expensive, and inherently dangerous. When Guizhou Transportation Group needed a safer and more efficient maintenance method, it adopted Kitefly Tethered's dual-tethered drone cleaning system: a complete solution integrating continuous ground power, high-pressure water delivery, and industrial aerial cleaning deployment. The system completed full operational testing and formal acceptance review, and all core performance indicators exceeded the original specification. What Is a Dual-Tethered Cleaning System? Traditional cleaning drones may carry a spray nozzle, but battery endurance and water pressure at altitude quickly become limiting factors. Kitefly Tethered addresses both issues at the same time through a dual-tether architecture: Power tether - continuous 380V ground power feeds the drone and onboard systems without battery-duration limits. Water tether - high-pressure water is delivered from the ground pump to the airborne spray lance, maintaining stable pressure at working height. The result is a system capable of 24+ hours of continuous operation, spray pressure up to 20 MPa, and cleaning efficiency of 800-1,000 m² per hour, while keeping all personnel on the ground. System Configuration This deployment integrates four core components from Kitefly Tethered's product line together with the DJI FC100 heavy-lift aerial platform. Ground Power Unit - G40Pro Tethered Power Box The G40Pro converts standard 380V three-phase grid power into regulated high-voltage DC output for the drone and all airborne systems. Key Parameter Specification Input Power 380V AC (3-phase, 4-wire) Output Voltage 0-1000V DC (adjustable) Rated Output Power =97% Protection Rating IP65 (partial components IP67) Operating Temperature -26°C to +40°C Storage Temperature -40°C to +65°C Altitude Rating 0-3,000 m Weight =95% restored Personnel working at height Zero Continuous operation (no fault) Full-duration test passed Compliance with safety standards Full pass Operational Advantages Unlimited endurance. Grid-connected ground power eliminates battery swapping and return-to-home interruptions. The system can support 24+ hours of continuous operation, making it suitable for full-facade cleaning tasks. No workers at height. All personnel remain on the ground and operate the system remotely, removing rather than merely reducing fall risk. Stable pressure at altitude. The ground pump delivers sustained high-pressure water to the airborne spray lance, while the integrated tether arrangement helps maintain continuous cleaning performance. Access to complex geometry. The telescopic AF-Q2 lance improves reach for recessed joints, curved curtain wall sections, and other hard-to-clean areas. Cleaner and greener operation. No fuel combustion is required during operation, and the process is compatible with green construction and maintenance requirements. Application Scenarios This system is intended for large-scale facade cleaning and infrastructure maintenance projects where conventional manual methods are unsafe, slow, or operationally impractical. Super high-rise office towers and commercial complexes Transportation hub terminals and stations Large-span glass atrium structures Bridge cable cleaning and surface maintenance Tunnel interior wall cleaning Industrial facility exterior maintenance About Kitefly Tethered Kitefly Tethered develops and manufactures tethered power systems for industrial drone operations.
