Persistent UAS

Orion 2 UAS – Advanced Tethered UAS for Military and Government Agencies

The Orion 2 UAS (Unmanned Aerial System) is a next-generation tethered drone system that provides fully automated, continuous aerial day and night surveillance over large areas. With a Kevlar-reinforced micro-tether and simple push-button operation, Orion 2 can operate for 24 hours continuously at altitudes of up to 100 meters (330 feet).

The highly modular and portable system features hot-swappable arms and legs, and is IP54-rated for rugged operation in challenging environments.

Gimbal-stabilized payloads provide crystal-clear imagery with low latencies and interference-free data transfer. With extended detection ranges of up to 10 kilometers or within 300 square kilometers, the Orion 2 is ideal for a variety of ISR (Intelligence Surveillance and Reconnaissance) needs, including military operations, special forces, law enforcement, public safety entities and private security.

Orion 2 features advanced Persistence Focused Safety Architecture (PFSA), and includes double or triple redundancy at every level, an intelligent safety battery, a secure datalink and an automatically-deploying smart parachute.

Tethered Drone Stations

Rugged drone tether systems for a wide range of secured UAS

Safe-T 2 – The First Smart Tethered Station for Drones

Safe-T 2 - Smart Tethered Drone Station
Safe-T 2 is an advanced tethered station for UAVs, offering real-time persistent observation and surveillance capabilities at altitudes of up to 125 meters above ground. Compatible with commercially available drones and payloads on the market, the system is especially suited for day – night aerial surveillance and telecommunications (Fibre optics, 4G, Wi-Fi, radio).

Rugged IP54 Drone Tether StationDesigned for the most demanding missions, Safe-T includes the IP54 rating and has been approved for tethered flights by an official rule-making body; the DGAC (French civil aviation). It has been successfully deployed by government bodies and industrial companies over 5 continents.

The modular metallic structure and fastening rails allow seamless integration into both vehicles and fixed structures.

Portable drone tether station

Safe-T 2 provides a new Dual-Comms option that allows UAV operators to deploy Fiber Optic and BPL data links in parallel, providing redundancy as well as versatility for different operations. Low latency and high-speed data exchange makes the Safe-T 2 ideal for telecoms and broadcast operations.

Tethered drone station with swappable microtether

The versatile tethered UAV platform provides up to 125m (400 ft) of adaptable micro-tether length, with easy in-field tether swapping allowing operators to optimize weight and power for each drone.


  • Power Output: 2200W continuous / 2800W peak
  • Micro-tether Length: Up to 130m (425 ft)
  • Operational Temperature: -10° to 45° C (14° to 113° F)

Ligh-T 4 – The Tether Station for all your Missions

Ligh-T 4LIGH-T V4 Drone tether is a mobile, rugged tethered drone station designed for deployment in the most demanding of environments.

Compact, easily carried and quick to deploy, the Ligh-T system offers continuous aerial observation capabilities to drone operators.
The kevlar-reinforced micro-tether provides a persistent and highly reliable power and data connection between the UAV and ground station.

Ligh-T Tethered drone station

An up to 200 Mbs link allows operators to seamlessly control a wide range of drones, such as the DJI Inspire 1, as well as transmitting high-resolution streaming video and image data. And the vertical spool structure provides enhanced weather resistance.

A built-in Wifi connection provides monitoring of live telemetry, logging and smart status alerts via the Elistair T-Monitor application.

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:

Private & Public Safety:
Our solutions can be quickly deployed by a single operator in a matter of seconds, to give an immediate and overall view of the area. They provide persistent coverage for police, first responders and crisis response that is both more discreet and more cost-effective than manned aircraft.

Tethered Drone for Public Safety

Defense Applications:
Providing continuous aerial surveillance, both day and night military tethered UAS can be easily carried, deployed quickly with little or no piloting skills and can fly for several hours consecutively. Real-time images are provided instantly and securely through the tether, allowing defense units to make quick decisions using detailed knowledge of their environment.

Tethered Drone for Humanitarian Needs

Humanitarian Efforts:
Drones have proven to be critical assets for emergency operations. They offer an immediate view across inaccessible areas, in most weather conditions, helping teams to spot dangers and victims, and coordinate an appropriate response.  They can be deployed for long-term operations, either covering large areas for several hours, or focusing steadily on specific areas that require precise analysis.

Tethered Drone for Humanitarian Needs

Tethered drones can create temporary, wide-range networks for propagation of cellular, Wi-Fi, high-frequency radio and 3G/4G signals.

Tethered Drone for Telecommunications

Traffic Monitoring:
Secured UAVs are compact easy to transport and deploy, and can provide valuable traffic data (trajectories, behaviours, vehicle types etc.), to networks, transport operators and public authorities to answer mobility challenges.

Tethered Drone for Traffic Monitoring

News Gathering Applications:
Unlimited 4k aerial video streaming, ideal for sports and other outdoor events, is possible with our tethered UAV systems.
