Tethered Drone Popular Science Q&A

A tethered drone connects to a ground power supply and control unit via a high-strength optoelectronic composite cable, enabling continuous power supply, low-latency data transmission, and stable hovering. It offers significant advantages in long-duration fixed-point operation scenarios and serves as a crucial supplement to traditional battery-powered drones. Below are the core Q&As.

Q1 What are the core differences between tethered drones and regular battery-powered drones?

• 1.Power Supply & Endurance: Regular drones rely on on-board batteries with a typical endurance of 30–60 minutes; tethered drones receive continuous power from ground municipal electricity or generators, theoretically capable of 24/7 non-stop air residency, limited only by ground power supply and cable durability.
• 2.Payload & Stability: Tethered drones eliminate the need for heavy on-board batteries, freeing up more payload capacity for optoelectronic pods, communication base stations, fire-fighting equipment, etc.; the cable provides physical constraint, offering superior wind resistance and hovering stability, suitable for high-precision operations.
• 3.Data & Safety: The optoelectronic composite cable enables simultaneous transmission of high-definition video and sensor data with low latency and anti-interference; cable constraint reduces the risk of uncontrolled crashes, and combined with backup batteries and emergency parachutes, it delivers higher safety.

Q2 What are the main components of a tethered drone system?

A typical system consists of three core modules, all indispensable:

1.Aerial Platform: Mostly multi-rotor (some compound-wing), featuring redundant design and high-precision flight control, with reserved payload interfaces and power/fiber optic channels.

2.Tether Cable: A high-strength optoelectronic composite cable integrating power supply, data transmission, and physical traction functions, meeting industrial-grade requirements such as wind resistance, flame retardancy, and wear resistance.

3.Ground System: Power supply unit (municipal electricity, generator, emergency power supply), cable winding/unwinding device, control station, and monitoring terminal; some support rapid deployment and vehicle/ship-mounted installation.

Q3 Which scenarios is it suitable for? Which are not?

• 1.Suitable Scenarios (High Match): Emergency communication relay, long-duration aerial monitoring/security, emergency lighting/broadcasting, continuous fire suppression, wind power inspection, environmental monitoring, temporary base station coverage, and other scenarios requiring long-duration fixed-point operations.

• 2.Unsuitable Scenarios (Low Match): Long-distance large-scale mapping, high-speed maneuverable reconnaissance, long-distance navigation in complex terrain, and scenarios without ground power supply or open operational space.

Q4 Is deployment and operation complex? Can ordinary people operate it?

1.Deployment Speed: Industrial-grade products can usually be set up and launched within 5–10 minutes, with some emergency models even faster; vehicle-mounted/portable designs further enhance deployment efficiency.

• 2.Operation Threshold: Supporting one-key takeoff/landing and autonomous hovering, operators do not require professional drone pilot qualifications; after short-term training, they can focus on payload operation (e.g., monitoring, communication relay, fire fighting).
• 3.Essential Inspections: Before each launch, check cable connections, power supply stability, cable winding/unwinding device status, surrounding obstacles, and no-fly zones to avoid safety risks.
