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.

Our 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.

SAFE-T is a station designed to transform existing drones into tethered UAVs, for surveillance and telecommunications.

Rugged and Field-Proven

Deployed by end-users since 2014 all over the world, Safe-T is truly field-proven. We have 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.
