Over the course of six decades, TESAT has developed in-depth expertise in manufacturing of payload equipment for communication satellites and has established itself as a clear European market leader. On its 60,000m² premises in Backnang, Germany, about 1,100 employees develop, assemble, integrate, and test systems and equipment for telecommunication via satellite. To date, more than 700 space projects have been completed.

Our product offerings encompass highly reliable equipment as for example the travelling wave tube amplifiers, multiplexers, waveguide switches, and modulators, which along with complete systems are delivered globally to all leading satellite manufacturers. Therefore, we offer the complete communication technology necessary, to for example emit television signals over the antenna of a satellite to each household. More than half of all communication satellites in orbit have Tesat equipment on board.

We are convinced that in future global communication will only be viable with the incorporation of space. Therefore, as the first organization in the world, we are developing and delivering equipment for optical broadband communication in space. Using laser, these terminals can transmit data and images between satellites and from satellites to earth. Advantages of laser communication are, for example, the high transfer rate of 5.5 Gbps (equivalent to 200,000 pages of information per second) and its stability.

Given our competitive position in the commercial satellite market and the quality standards required of us there, our products are now used more frequently in the various satellite-based systems of the security and defense sectors in Germany, Europe, and the United States.

In addition to our technical expertise, we cultivate our standing in Backnang through social engagement and by supporting public projects.

  • In space communication, we pioneer with passion and strive to be the number one partner for your success. Our solutions set standards that open borders, and connect people worldwide.

  • TESAT understand itself as Europe's largest equipment supplier in the field of satellite communications and serves the global market with a regional emphasis on Europe, North America, and the Far East.

    The market for satellite communications can be essentially divided into three segments:

    • commercial applications
    • civil applications e.g. earth observations for scientific purposes,
    • exploration of space and military communications, such as remote sensing

    The most important application for commercial satellite communication is the distribution of TV channels that are received in tens of millions of households via satellite system operators, either directly or through cable networks. They allow direct transfers of news and sports programs. But also the development of devices for data and video communications has changed the applications of communications satellites in different market segments significantly.

  • Conflict Minerals Policy The ongoing conflict and extreme violence in the Democratic Republic of the Congo (DRC) is fueled in part by the trade of "conflict minerals", which are defined as tantalum, tin, tungsten and gold as well as any of their derivatives (3TG).

    Since Barack Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection Act in 2010, every company traded on American stock exchanges has been required to look into the origin of conflict minerals in their supply chains and report on the reasonable inquiry and due diligence in order to determine whether their purchases supported armed groups in the DRC and adjoining countries.

    Consequently the U.S. law mentioned above does not only impact U.S. companies but a much larger number of companies worldwide.
