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.
