We Connect in space

We deliver innovative solutions for satellite communications. For everyone. For a better world.

Data transmission via satellite is indispensable for sustainable development. We supply the key components for satellite communications technology and are continuously improving them. As the leading manufacturer of secure space-based communications, we are helping to connect the world and make it a better place to live.

Every day, we are working hard on our contribution to sustainable development:

  • We help people to connect (telephony), stay informed (satellite TV, internet for remote areas), and find their way (navigation).
  • We enable better earth observation for climate, disaster prevention, security and higher yields in agriculture.
  • We contribute to scientific progress. We cooperate with universities and serve various scientific projects such as the James Webb telescope.

On our 63,000m² premises in Backnang, Germany, about 1,100 employees develop, assemble, integrate, and test products, systems and solutions for satellite communications. To date, nearly 1,000 space projects have been completed. More than half of all communication satellites in orbit have TESAT equipment on board.

We offer the complete communication technology necessary, for example to emit television signals via satellite antennas to each household. As the first organization in the world, we have been developing and delivering equipment for optical broadband communication in space. Advantages of laser communication are the high data transfer rate, its transmission security and its stability. More than 85,000 laser transmissions have been successfully performed so far.

From a social point of view, we value different perspectives, backgrounds, experiences, skills and individual qualities. Together, we stand for a culture of open discussion, integrity, focus, entrepreneurial thinking and action, and leadership by example.

Environmental protection and the economical use of resources are part of our daily activities, from product development to production.

In short: We are shaping the future of communications. For our employees, for our customers, for our partners, for everyone. For a better world.

  • In space communication, we 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.


  • Quality in a nutshell

    • EN 9100 certified management system
    • Direct reporting line to the CEO
    • Materials, components and production processes are based on ECSS-Standards
    • ESA qualified lines for PWB production and PCB assembly
    • ESA Capability approval for the microwave manufacturing Line,
