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.

frequency
Wired data link (no RF emissions for control)
cost Estimate
$20,000–$200,000
altitude
50–150 m (limited by tether length)

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
