The First Smart Tethered Station for Drones

Safe-T is an industrial smart tethered station for UAVs, offering real-time semi-persistent observation and surveillance capabilities thanks to its patented micro-tether.  Offering the widest range of compatible drones and payloads on the market, the system is especially suited for:

  • Persistent Aerial Surveillance (Day and night)
  • Temporary Telecommunications (4G, Wi-Fi, radio)
  • Industrial Inspections

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

Unlimited Flight Duration

A direct power supply from the ground station through the micro-tether provides the drone with unlimited endurance.

Elistair’s compact smart Onboard Module replaces your battery, resulting in a continuous, reliable, and secure power source. Connected to the electrical grid or to a generator, Safe-T is designed to run from several hours to several days.

No drone modifications are required, enabling you to switch from tether mode to battery mode in seconds, for a greater versatility.

Safe and Connected

Providing a continuous and redundant power supply, secured by an UPS safety battery, the Safe-T micro-tether is armored with kevlar to withstand over 1000 Newtons of traction, and provides an unbroken and unjammable data transfer.

Integrated with various sensors, the Safe-T is continuously self-checking its status and uses fail-safe procedures in case of anomalies.  An embedded WIFI module streams the system status to Elistair T-Monitor application, allowing the operator to monitor its operations from a tablet or PC.

The system allows for safer missions in complex scenarios, with a complete protection of surrounding equipment and people, and has been certified to be in adequation with Civil Aviation laws.

Rugged and Field-Proven

Deployed by end-users since 2014 all over the world, Safe-T is truly field-proven.  Elistair has worked hard to make this powerful tool rugged, compact, easy to use and quick to deploy on the field by a single operator.  The system fits easily in standard transportation means.

The smart Onboard Module is compact and can fit in the common battery space of your drone. Easy to connect / disconnect, you can switch from free flight to persistent flight in seconds.

Safe-T incorporates a proprietary software, with fine-tuned control laws limiting the impact of the micro-tether on the drone flight and preventing entanglements or wear risks.


Rugged Tethered Station for Drones

Ligh-T is a compact and robust tethered station for drones. Designed for demanding missions in all environments, it offers continuous aerial observation capabilities to drone operators, public safety, private security, traffic monitoring agencies, national security and law enforcement units.

Ligh-T has been built as a rugged and mobile solution, and is based on Elistair proprietary micro-tether technology.

Quickly connected to wide range of drones as the DJI Inspire 1, the Ligh-T is the perfect tool to enlarge your drone potential thanks to unlimited autonomy and increased safety.

Compact and Powerful

Drones are know to be easily transportable, quick to deploy, and flexible.  Tethered stations should be too.  That’s why Elistair created this compact, simple, but powerfull solution.

Easily carried by a single operator, its vertical spool structure allows for fast deployments and grants a great weather resistance.

Ligh-T enables you to tether/untether your drone at will, in the blink of an eye, with its smart Onboard Module replacing your battery.

Connected and secured

Ligh-T is based on Elistair micro-tether proprietary technology. Extremely light, it offers unlimited and reliable power supply and safer flights thanks to its kevlar core.

Now featuring a secured data connection through the micro-tether, at 60 Mbs, you can use Ligh-T to control your drones, or transmit the drone camera videostream through the micro-tether.

A built-in Wi-Fi is integrated for live telemetry, logs saving, and smart alerts thanks to Elistair T-Monitor application.


Persistent Aerial Surveillance

Elistair’s  tethered drone solutions are critical asset for security operations. The continuous and global aerial view enables long, risk-free and efficient surveillance for both night and day use.

Using tethered drones as virtual ‘Surveillance Towers’ is a simple and efficient solution for semi-persistent applications, with a serious cost advantage over helicopters or manned aircraft.  Tethered UAVs can be deployed for long-term operations in order to cover a large area for several hours.  Compact, lightweight and quick to deploy for a single operator, tethered UAVs make little noise from a high position, ensuring discreet surveillance.

Elistair’s tethered systems are best suited for police forces, public safety operations, firefighting, crisis monitoring or military operations.

Industrial Maintenance

Remote inspections of industrial structures and facilities are often costly, hazardous and sometimes impossible to achieve.  While the fast growth of unmanned systems soutions is offering an answer, free-flying drones are still limited to a fraction of their potential in industrial maintenance, because of their limited flight time and their low safety level.

Elistair tethering solutions dramatically increase the safety of drone operations through a reliable power supply and secured communications.  Immune to interference and scrambling, battery failures and fly-aways, our systems allow safe and efficient commercial inspections, in a variety of demanding industrial environments as airports, wind farms or refineries.

Operating in a volume of operation mastered by the micro-tether, industrial companies and drone operators now beneficiate from a full-control on their flights, facilitating the maintenance and the protection of their assets.


Tethered UAVs are powerful tools for telecommunications, acting as airborne antennas.  They enable the creation of temporary, wide-range networks: cellular, wifi, high-frequency radio and 3G/4G signals.

Thanks to their high-speed data transfer, our tethered systems are particularly suited for pop-up telecommunications.

They have many applications, such as emergency situations, crisis monitoring, firefighting, large events coverage and humanitarian missions.

Continuous Aerial Broadcasting

Perfectly suited for sports broadcasting, Elistair tethered systems provide a rich aerial perspective to live filming. Tethered UAVs can revolutionise the entertainment industry by allowing unlimited aerial coverage with high quality aerial live shots, and the best safety standards.

Tethered UAVs are key assets for increasing your audience through immersive aerial filming on large outdoor events like concerts and sports competitions.  By offering a safer and unlimited aerial video-stream to producers, Elistair’s systems bring innovative and visually rich aerial perspectives to live productions.

Traffic Monitoring

Due to an increasing number of vehicles on roadways, better traffic management and planning have become imperative.

Elistair’s tethered solutions offer continuous and real-time aerial video-stream, allowing persistant data collection and analysis.  A tethered drone is a compact tool, easy to transport and deploy, that gives access to various valuable traffic data (trajectories, behaviors, vehicle types etc…), which are crucial information for individual end user (drivers), networks and transport operators or public authorities, to answer mobility challenges.

Count, measure and analyse in order to understand road-user behaviour, analyse trajectories and detect anomalies. With the deployment of a single UAV during several hours, continuously, get a more comprehensive look at traffic nodes.

Air Quality Monitoring

Monitoring air quality and pollution is crucial to understand our cities and industries, and to prevent public health incidents.  Elistair’s tethered systems allow for simple and reliable data collection in three dimensions.

Elistair’s tethering stations provide unlimited access to remote locations and hazardous areas at a low cost.  Employing advance technology, drones can easily collect samples of compounds such as:

  • Volatile Organic Compounds
  • Ozone
  • Sulphur Dioxide
  • Nitrogen Dioxide

The high-speed data transfer made possible by the micro-tether, allows for real-time data collection and analysis in a fast and secure way.

Some other applications:

Meteorological measurements

Continuous gas sensing

Energy & Utility industries monitoring

Chemical industries monitoring

Particulate matter measurement

Integrated gaseous sampling

Thunderstorm and tornado monitoring

Biological & Nuclear threats identification
