Tethered Surveillance Drone

Tethered DroneThreat: Low

A multirotor drone connected to a ground station by a power/data cable, providing virtually unlimited endurance. Acts as a persistent elevated sensor platform — a poor man's aerostat. Used for perimeter security, base defense, convoy overwatch, and event surveillance.

Technical Specifications

range
0 km (stationary — tethered to ground)
speed
0 km/h (stationary hover)
payload
2–10 kg (cameras, sensors, relays)
endurance
24+ hours (continuous power via tether)
frequency
Wired data link (no RF emissions for control)
cost Estimate
$20,000–$200,000
altitude
50–150 m (limited by tether length)
weight
5–25 kg (drone only)

Tactical Roles

ReconnaissanceISR

Advantages

  • + Unlimited endurance — powered from the ground
  • + Persistent overhead ISR without crew rotation
  • + Wired data link — immune to RF jamming
  • + Lower cost than manned aircraft or aerostats
  • + Quick deployment for temporary surveillance
  • + Can carry comms relay equipment for extending range

Disadvantages

  • Stationary — cannot maneuver or reposition quickly
  • Tether limits altitude and is a physical vulnerability
  • Easy to detect due to static position
  • Vulnerable to small arms, snipers, and artillery
  • Limited to base/perimeter defense roles
  • Wind and weather affect stability

Real-World Usage

  • Elistair Orion — tethered ISR used by French and US forces
  • FLIR SkyRanger tethered variant for base protection
  • Israeli military using tethered drones along borders
  • Used at major events (Olympics, summits) for security surveillance
