What STT-SystemTechnik GmbH does
STT-SystemTechnik GmbH is a privately held German SME founded in July 1995 by Peter Taubenreuther and headquartered in Munich. The company designs and manufactures RF/microwave communication hardware for space, defense, and industrial telemetry applications, with product lines spanning TMTC (telemetry, tracking, and command) units (SSTRC series), high-data-rate transmitters (PDTX series), multimode S-band/X-band transmitters (TS series), receivers, antennas, and sensors. Its technology has accumulated flight heritage on more than a dozen satellite and sounding-rocket missions including TerraSAR-X, AGILE, PROBA-2, GRACE-FO, SAR-Lupe, SARah, NAOS/LUXEOSys, and MAPHEUS-16.
The company operates a high-value, low-volume business model, selling bespoke or short-series RF subsystems to space agencies (DLR, ESA, NASA/JPL, ASI, Hisdesat, NSPO), system primes (Airbus Defence and Space, OHB, Saab, MBDA), and emerging in-space service operators (ClearSpace). With a headcount of roughly five employees, STT functions as a specialist engineering boutique rather than a volume manufacturer, leveraging flight-qualified designs and German-built quality positioning. Distribution is handled partly through partners such as Columbia Research in the United States and EIDEL in Norway, supporting international program delivery.
Commercially the firm is bootstrapped and founder-controlled, with no disclosed external funding rounds. Revenue is generated primarily through engineering services, qualification programs, and hardware deliveries tied to individual satellite or missile programs, with long product lifecycles and customer relationships that often extend across multiple missions per platform.
