Tethered UAV power supply station enabling continuous flight for emergency rescue, power inspection, and communication support through ground-to-air power conversion and intelligent tether management.

LeVane Power Tethered Drone Ground Stations – Unlimited Flight Time, Uninterrupted Missions

A tethered drone ground station—also known as a tethered power unit or tethered base station—is the essential ground-based support system that keeps drones flying for hours, not minutes. By delivering continuous, stable power through a lightweight tether, it completely eliminates the battery limitation that has long plagued the drone industry: limited flight time.


What Is a Tethered Ground Station and How Does It Work?

Simply put, the tethered ground station converts ground power (from the grid or a generator) into high-voltage DC electricity and sends it up the tether to the drone's onboard power system.

Here's how it works, step by step:

  • Power Conversion: Takes single-phase 200-240Vac or three-phase 380Vac input and converts it to 800-1400Vdc high-voltage DC.

  • Power Delivery: Transmits both electricity and data through a single hybrid tether cable that combines power lines with fiber optics.

  • Automatic Tether Management: A smart winch system automatically pays out and retrieves the tether as the drone ascends or descends—no manual handling required.

  • Onboard Conversion: The drone's onboard DC-DC converter steps the high voltage down to the low voltage the drone actually needs (such as 24V, 48V, 50V, or 100V).


What's Inside a Tethered Ground Station?

Modern tethered ground stations come in either integrated or split-configuration designs. Here are the core components and what they do:

ComponentFunctionKey Feature
Power ModuleConverts AC to high-voltage DCHigh power density, 96-97% efficiency
Tether Management SystemAutomatically deploys and retrieves the cableOvercurrent, overvoltage, short circuit, and overtemp protection
Tethered CableHybrid fiber-optic + power cableWithstands ≥2000V, available in 110-220m lengths
Control SystemMonitors and protects the entire unitOne-touch start, auto voltage compensation, fault self-recovery
EnclosureRugged protective housingIP43 rated; backpack or wheeled options available

For high-power systems above 25kW, we typically use a split-configuration design that separates the power supply unit from the tether winch—improving heat dissipation and making transport much easier.


Why Choose LeVane Power Tethered Ground Stations?

At Shenzhen LeVane Energy Technology Co., Ltd., we've engineered our tethered ground station series to deliver where it matters most: real-world missions.

1. Unlimited Flight Time

  • Keep drones airborne 24/7—no more battery swaps, no more landings to recharge.

  • Perfect for emergency communications, disaster monitoring, and any scenario where every minute counts.

2. Built Tough, Tested Tougher

  • Every unit undergoes automotive-grade validation: EMC testing, thermal cycling, HALT (Highly Accelerated Life Testing), and MTBF reliability analysis.

  • Comprehensive protection suite: overcurrent, overvoltage, short circuit, and overtemp safeguards.

3. Smart Control, Simple Operation

  • One-touch start with automatic voltage compensation.

  • Intelligent tether management: passive pay-out, active retrieval at ≥2m/s.

  • Real-time monitoring of voltage, current, tether length, and system temperature.

4. Built to Move

  • Choose backpack-style units for long-distance carrying by a single operator.

  • Or opt for wheeled, pull-handle cases for rapid deployment—set up in just 15-30 minutes.

  • Compact form factor easily moves across rough terrain.

5. Safety First, Always

  • High-voltage and low-voltage circuits are physically separated to eliminate interference.

  • Reliable grounding with dedicated terminals on the enclosure.

  • Smart retrieval stops automatically before full retraction, preventing damage to connectors.

Quick Tips for Safe Operation

To get the best performance from your LeVane Power tethered ground station:

  • Position it right: Place the unit on a level, stable surface before operation.

  • Gear up: Operators should wear insulated gloves as a safety precaution.

  • Smooth adjustments: Turn adjustment knobs slowly and gradually—no sudden jumps.

  • Protect the tether: Avoid dragging the cable across rough ground or sharp edges.

  • Post-mission care: Neatly spool the cable after use and keep the unit clean and dry.
