Tethered Drones

How can I increase flight time of drones?

With tethers that deliver power from ground.

How long is a tethered drone able to fly?

Because the power is transferred via the tether to the drone, power supply doesn’t limit flight time. However, the required maintenance of moving mechanical components (e.g: motors) is the only limitation.

How do you reduce possible hazards that come with flying machines?

The safest flight is always to not fly at all. However, we take care to increase redundancy to reduce hazards to man and machine: we have fallback systems, dead man systems, back-up motors, batteries and-so-on … powering a drone on tether is safer than a free-flying drone.

What’s the point about a multi-drone system?

Conventionally, you need one pilot per drone. For multi-drone systems you only need one pilot per system while a swarm of drones does the work in parallel (in law-abiding conditions). And if you need a training, we’ll provide you with it.

How do you measure the position of your drone?

We use sensor fusion based on a mathematical model of the drone. Different kinds of sensors are used to estimate the state of the drone including the position. GPS, Barometer, IMU and additional environmental awareness sensors.

What is the future perspective for drones?

Forecasts predict a massive growth of the drone industry. There will be two segments of drones that are going to take over jobs that human beings typically perform.

  1. Free-flying short-operation time drones that do short- to long distance deliveries, inspection, photography and entertainment.
  2. Drones that do physical long-operation time work (remote manipulation) and require extra power over tether.

While the market of free-flying drones is converging towards saturation in most of its possible segments, tethered drones are about to take-off and conquer their segments

Technical & Electronics

Is your control framework limited to drone systems?

Of course not. Once a system can be described by a physical model sufficiently accurate, our system is able to handle it.

What kind of embedded processors do you use?

We use different types. Most operations, as well as control algorithms, run on ARM Cortex M7

Do you test your embedded code?

We test our embedded code in several stages. A very prominent part in the testing workflow lays on our automated continuous integration system. Besides static code analysis and compilation, the system also enforces code quality. We use unit tests for a large part of the code base. To check the integrity of the resulting firmware binaries, the system loads them onto attached electronics and performs benchmark tests. Additionally, the higher-level parts of the firmware can be compiled for Linux x86 systems and then be used to simulate the electronics behavior.

How do you control drones?

Self developed model-based control scheme based on advanced control theory.

Possible Applications

Can you help us make Application X go airborne?

Anyone with a proposal within the boundaries of physical feasibility is welcome. Besides our complete tether technology package containing all required hard and software, our R&D team assists you with hard- and software integration by finding, designing, offering the required interfaces to making your project work.

What can you do for us?

Our core competence is swarm control of physically interconnected hovering drones. Our technology is based on a modular platform consisting of all required hardware, electronics, embedded firmware, high-level controls, signal filters and user interfaces. Everything is designed and built with a constant eye for quick customization.

My current machines can’t drive on a steep plot of land. Do you have a solution that’s easy to operate without a degree and equally easy to maintain?

We plan to sell complete, easy to use drone systems that are able to spray crop protection and monitor your plants from the air. It will be fully customizable to your needs and you will be able to maintain it yourself.

I am willing to build a drone myself, but off-the-shelf hobbyist components are too constraining. Do you offer an alternative?

Yes, we offer self developed model-based control schemes based on advanced control theory as well as matching electronics for standard functionality.
