what are the benefits of using a tethered drone?

Increased endurance, secure data, and safer flights.

A tethered drone is a drone which is connected to a power station on the ground. Often, the drone is connected by a wire, which can be stretched to a certain height and can be used to transfer data, safely and securely.

Tethered drones trade lateral movement for increased endurance as they are physically and securely connected to a ground station by a micro-tether, essentially providing unlimited flight time. This is compared to the average 25-30 minutes of flight time of a conventional drone flying without tether.

The tether not only provides the physical security of keeping the UAV in place but also provides power and in some cases the ability to transfer secure data which, because it is not being transmitted by radio frequency, cannot be jammed.

A tethered solution has multiple benefits for a wide range of industry verticles. These benefits include:

  • Persistent: Connected to the micro-tether providing power from the ground, drones are able to remain airborne for hours.
  • Cover Wide Areas: With operational heights of 50 to 100 meters, tethered UAVs can provide wide coverage of large events.
  • Secure: The micro-tether provides secure, unjammable, communications immune to interference and enabling a safe, real-time, high-speed data transfer.
  • Overt Deterrence: Tethered UAVs provide an overt surveillance deterrent which disrupts an adversary's freedom of movement and action.
  • Functional: Robust and easily transportable, tethered systems are designed for the field. Quick to use and deploy, it is a simple and effective solution for persistent aerial surveillance.
  • 4K Video Streaming: Secured 4K aerial video-streaming is made possible thanks to Elistair’s micro-tether. The tethered systems allow continuous and interference-free high-quality video broadcast.
  • Flight Safety Assurance: In crowded entertainment events public safety is essential for risk holders. Elistair tethered technologies ensure safe drone operations through a fully controlled and physically secure system.

How industries are utilising drone tethers

Elistair's tethered drone systems are being deployed for a variety of applications across the world. Here is a breakdown of how certain industries are benefiting from a drone tether.

Government and Defence: A tethered drone can be used for tactical operations monitoring, observation and compound surveillance, and pop-up telecommunications. A tethered drone allows Force Protection Units to make rapid tactical decisions with detailed knowledge of the environment, while high-speed data transfer is suited to pop-up telecommunications in emergency situations. Elistair's tethers can also be easily transported and quickly deployed. 

Public Safety: Public safety crews are deploying tethered drones for a variety of missions, including crisis management, crowd control, firefighting, search and rescue, and emergency telecommunications. A tethered drone is a valuable asset for public safety. As a quick and easy deployment solution, a tethered drone reduces the need to send out a helicopter - which can be a costly alternative. Public safety crews can also access live, airborne images of a scene - ideal for crowd control, surveillance, and evidence gathering.

Telecommunications: A drone tether can be used for pop-up telecommunications and disaster recovery. A tethered drone system is a powerful tool for telecommunications, acting as an airborne antenna, and enabling the creating of temporary networks including cellular, WiFi, high-frequency radio, and 3G/4G signals. The high-speed data transfer of a tether is also well-suited for pop-up telecommunications. When deployed to a disaster area, tethered drones relay immediate images of the area, helping rapid assessments and decision-making.

Traffic Monitoring:  Tethered drones are a key tool for transport operators and public authorities. Because a tethered drone system supports prolonged airtime, this solution can be used for continuous and real-time aerial traffic monitoring, allowing detailed data collection and analysis, which can then be used to drive decision-making.  

Humanitarian Needs:  In times of disaster, a drone tether can be a decisive and critical asset for first responders, local authorities, and governments. A tethered drone system can be deployed to provide an immediate viewpoint of a disaster zone, including inaccessible areas, and utilised to spot casualties, identify dangers, and highlight safety routes - essential for an effective response, and to improve the safety of rescue crews. A tethered drone can also be deployed for a long time, is easily transportable, and can handle demanding environments, making it the ideal solution in the wake of a disaster. Thanks to a tethered drone's ability to act as an airborne antenna, enabling the creation of temporary networks, this solution can be used for emergency and pop-up telecommunications.    

TV Broadcasting:  By deploying a tethered drone, media professionals are able to capture stunning aerial footage of major sporting events and concerts. The drone can be airborne for hours, ensuring none of the action is missed, and the tether provides a safe way to capture live footage.
