Elistair is a leading designer and manufacturer of innovative tethered drone systems for defense and commercial applications.

Founded in 2014 with offices in France and Boston, Elistair develops tethered UAS (unmanned aerial systems) and powered tethering stations for third-party drones. These solutions turn small multi-rotor vehicles into airborne platforms for persistent surveillance and high-speed telecommunications, allowing military and civilian users alike to make better decisions with enhanced situational awareness.

Elistair’s products have been deployed with militaries, police forces, public security departments and private companies in more than 70 countries around the world. Our clients include the French Defence Agency, Thales, the US Army, the UK police, Total, Paris Airports, Securitas, ENGIE, and Vodafone.

Persistent Tethered UAS

Khronos

All-in-one tethered drone-in-a-box solution

Khronos is an all-in-one drone-in-a-box system that is designed for both fixed and mobile applications. Pairing an advanced quadcopter with a rugged IP54-rated base station, it provides instant aerial intelligence of the surrounding area, and can be deployed without leaving the vehicle.

The tethered drone provides up to 24 hours of persistent operation, with a tether height of up to 60 metres. It can be equipped with a choice of two stabilized EO/IR ISR gimbals, the NDAA-compliant NextVision Raptor or the DragonEye.

Applications

Our tethered UAS solutions are ideal for providing unlimited autonomy, power and data transfer, safely enabling persistent coverage for a wide variety of unmanned aerial applications. Use cases for our UAV stations include:

Military Drone Surveillance

Our tethered drone solutions enable persistent observation and surveillance of the battlefield, providing force protection and enabling operators to gather actionable intelligence and make critical decisions in highly challenging environments.

Tactical Communications

In addition to surveillance, tethered UAS can be deployed as variable-height antennas to enhance communications line-of-sight and increase range and connectivity, at lower SWaP-C compared to a traditional mast.

Border Protection

Tethered drones are ideal for covering wide areas of vulnerable borders, protecting against unauthorized crossings and criminal activities while reducing manpower and operator burden.

Event Security

Tethered UAVs are ideal for providing aerial overwatch of large crowds and public events, ensuring safety and providing critical information to security teams and law enforcement on the ground.

Traffic Monitoring

The increased safety and endurance of tethered drones make them highly suited for monitoring traffic, providing hours of data collection and analysis without the need to land and change batteries.

Industrial Surveillance & Monitoring

Our solutions provide efficient surveillance and monitoring of industrial sites and critical infrastructure, helping to prevent intrusion and spotting potential danger before it becomes serious.
