Tethered Drone Systems

The Future of Tethered UAV Technology

about us

Tethered Drone Systems (TDS) have created a Tethered UAV, the only one fully designed, developed and manufactured in the UK with its capabilities, with extended flight duration of 24 hours or more and with secure communication via the fibre optics.

TDS continues to develop a complete tethered drone platform with multiple payload options and secure communications via the high bandwidth fibre optic cable. In addition TDS has been engaged in a contract with the MOD for Navy X – (see News page) to develop a ground power, winch system with UAS power supply unit for a large drone platform. The video shows the size of the drone and the capability for large payloads, continuous flight and eventually operational deployment from a warship.

The extensive R&D phase has resolved many problems and taught TDS a great deal about this type of tethered drone capability, this learning will be now be engineered into the TDS platform to offer clients additional operational deployments and payload options to meet even the most extreme needs.

design and build

Initial R&D was undertaken by the renowned UAS engineers at the University of Southampton as a consultation project. TDS are now beyond R&D on the bespoke designs and development of upgraded power and secure data communication via the ground station and the TUAS.


TDS have been very lucky in having a lead investor like The British Robotics Seed Fund, not only have they invested cash but also considerable time, energy and ideas into the business, TDS has HMRC Advance Assurance for EIS investment funding and continues to seek investment groups or individuals, the current round can be reviewed via the following sites.

continuous flight

Free flying drones are ideal in many situations but not when the situation requires a continuous ‘on station’ solution that can remain in flight all day and all night. Carrying a payload to meet the situational requirements with fully autonomous flight. Ground generated power transmitted up the drones lightweight tether maintains a stable and constant flight ceiling ensuring the payload is deployed for the whole time it is required.


drone tether

The tether is very strong, lightweight and rated for high voltage power transmission, either mains or generated power. The drone tether is deployed via a TDS designed and developed intelligent powered winch with a strength capability of 1200N. The intelligent winch communicates with the flight controller to maintain the flight ceiling and GPS position at all times and in adverse weather conditions.


secure communications

The payload deployed is key and clients want the guarantee that all data transmitted both up and down the tether is totally secure. The transmission of telemetry data up and returning live broadband quality HD Video or data from on board sensors is FIPS compliant secure TLS encryption. There can be no data capture or telemetry jamming to compromise the operational deployment of this tethered drone.
