Tethered Drones: Bridging the Sky and Ground

  • A tethered drone is an unmanned aerial vehicle (UAV) connected to the ground via a cable or tether.
  • It comprises a ground-based base station and the drone, linked through this tether.

Power and Communication

  • The tether serves dual purposes, providing both power and data communication to the drone.
  • This arrangement enables the drone to operate for extended periods without relying on limited onboard batteries.

Operational Control

  • Tethered drones can be remotely operated to execute specific tasks, offering flexibility in their applications.

Advantages of Tethered Drones

  • Reliable Data Capture: Tethered UAVs excel in data capture and telemetry due to the dependable tethered connections.
  • Reduced Flight Risks: They significantly decrease technical and human errors, minimizing the likelihood of in-flight accidents.
  • Secure Communication: These drones establish a secure communication line between the ground station and the aircraft.
  • Interference Resilience: The physical tether connection makes tethered drones less susceptible to interference or hacking compared to wireless counterparts.
  • GPS Independence: They do not rely heavily on GPS navigation.
  • Extended Flight Times: Many tethered drones boast longer flight durations compared to free-flying, battery-operated drones.
  • Simplified Operation: Due to restricted movement, operators do not require advanced piloting skills and can focus primarily on task execution.
