TTTech Computertechnik

TTTech Computertechnik AG is the head office of the TTTECH group, a group of high-tech companies in Vienna, Austria. The address is Schoenbrunner Strasse 7, 1040 Vienna. The group focuses on safe and secure networked computing and safety control systems. It serves aviation, space, mobile machinery, industrial machinery, automotive and energy.

The site tells the story of the group. In 1998 Professor Hermann Kopetz, his son Georg and former student Stefan Poledna started the company as a spin-off of the Vienna University of Technology. The name first stood for Time-Triggered Technology. The company says it pioneered time-triggered networking, which lets machines talk in real time without failure. It says its systems now run in air and spacecraft, the energy industry, industrial automation and mobile machinery.

Recent news shows the aviation and space side of the group. In September 2026 TTTECH and its partner Beyond Gravity Austria reported full product qualification of an Ethernet based networking and computing platform for avionics in deep space and lunar uses. A July 2026 item covers MYTHOS network switches for onboard avionics on launchers, satellites and space stations. On 1 October 2026 the group set up a new subsidiary to focus on strategic markets.

The group lists several units at the same Vienna address. They are TTTech Systems SE, TTTECH Aerospace, TTTECH Industrial and TTControl GmbH. The site has a contact page with forms, a careers page and a page about quality and standards. The main phone number is +43 1 585 34 34 0.
