Yesterday Threod Systems performed a very successful test flight with UAS STREAM and integrated CORDIS ARRAY II communication solution in cooperation with Radionor Communication AS. A Norwegian company that provides data links for unmanned systems. The data links provide long-range broadband connectivity combining high-definition video transfer with sensor control, mission control. The technology is ideal for combining connectivity for all mission-critical functionality for unmanned data links such as bandwidth control, priority for critical data transfer, error-free UDP streaming and latency control. The smart antenna technology has an additional option for high-speed tracking of the UAV with high precision, and can be utilized for satellite independent navigation.

The Radionor CRE2-179-AERO was integrated to STREAM UAS and 15th of September, 2016 Threod performed a 100 km test flight. The result was more than satisfying – Radionor datalink system allows to reach way better results than the relatively short distance covered yesterday.

Threods’ CEO Villiko Nurmoja comments that: “We had high expectations and the solution proved itself, without a doubt, more than positively. In modern, highly competitive market of unmanned systems it is crucial to develop cross-border cooperation and find partners that offer best solutions on the market, and we are pleased that we found Radionor.” By combining exceptional solutions around the globe, Threod aims to create best UAVs with features surpassing the competition.

Previously head of business development at the unmanned aircraft manufacturing company Threod Systems Mr. Villiko Nurmoja recently took over the CEO position. Mr. Kristjan Tiimus will continue his role as the chief technology officer and the member of the board. Mr. Sten Reimann former CEO of Threod Systems will continue in Ukraine with his newly registered company Legio Group LLC and drive Threod products to the Ukrainian market.

Villiko Nurmoja comments that Sten Reimann has established a very strong foundation during the development stage and chosen an exceptional team of professionals. Company will continue to develop and produce unmanned aircraft systems and sub-systems. The next phase is to broaden cooperation network on the international market and to bring Threod products closer to the end-user.

Threod Systems was established in 2012 as a company specializing in the field of unmanned aircraft system development and production, by today there are five unmanned aerial vehicle platforms and multiple sub systems and support equipment, with the highlight on the optical observation sensors, control stations and autopilot, developed with support of the ministry of defense of Estonia. For instance, among other achievements, Threods’ unmanned aerial vehicles support NATO KFOR operations in Kosovo.



Threod EOS Mini-UAV supported Defence League battalion operations. Equipped with a new EO/IR gyro-stabilized gimbal Threod UAV brought the operation C2 to a totally new level. The clear and stable imagery provided best situational awareness for the quick decision making. Implementing EOS Mini UAV thought out the battalion operations enabled to gather tactical level intelligence, as new generation EOS Mini-UAV solution brings tactical UAV capabilities down to Mini UAV level.

Threod Systems made it to IHS Jane's and reffered to as an unmanned know-how.


"Although the company is only four years old, Threod Systems from Estonia has built up expertise in unmanned air systems, not only producing the vehicles itself, but also engineering the associated ground control systems, autopilot, sensor gimbals and engines. The company’s EOS mini-UAS has been used in support of ISAF and KFOR operations in Afghanistan and Kosovo, respectively, while its products are the subject of a number of tenders.

To date Threod (Hall 5, Stand J521) has flown five vehicle types, including the multi-rotor KX-4 and KX-4LE, EOS hand-launched mini-UAS, and the runway/catapult-launched Stream. The largest vehicle is the Theia, a wheeled 100kg UAV with an endurance of 24 hours and the ability to carry a 25kg payload. The air vehicle has been flown in concept demonstrator form as the Theia 1, and in the next few weeks the operational Theia 2 is due to fly, this version featuring a wider fuselage to accommodate a large gimbal payload. Power is provided by a 110cc petrol engine, a Honda unit rebuilt by Threod.

Threod has also developed its own gimbal systems. An EO/ IR dual-sensor system is for the smaller vehicles, to which a laser rangefinder and IR illuminator are being added yet still keeping weight below 1.5kg. A 2.4kg three-sensor payload is employed by the larger vehicles.

Related systems are applied across the family, including a highly advanced adaptive, triple-redundant autopilot."


Unmanned know how Threod UAS

A renewed cooperation agreement was signed between Threod and Aviation Academy. Both parties share mutual beneficial interest in the fields of UAV technologies, aviation flight regulations and safety. Unmanned systems have been a highlight for the Aviation Academy students and cooperation will ensure an exchange of both theoretical and practical experiences. 

simulation environment developed by Threod has now been set up in the Aviation Academy. It allows to conduct training in unmanned systems operations on a totally new level, including UAV flight mission planning and UAS management. It can also be used for research purposes, system integration and testing as well as developing new solutions. Future plans are to create an unmanned aircraft test centre and prepare UAV operators to fly aircrafts of different categories. 

Threod Systems performed a demonstration flight on Tartu International Airfield. A fully integrated system was presented: a tactical level air vehicle and a vehicle based ground control station.

In addition to Threod Systems and Estonian Aviation Academy personel, high-level guests from Ukrainian Antonov State Company were also present during the flight demonstration.
