Reference excerpt

The Tesat-Spacecom GmbH & Co. KG (TESAT) from Backnang, Germany is an independently operating subsidiary of Airbus Defence and Space which develops, produces and tests communication payloads for international satellite manufacturers.

History

In 1949, the AEG (Allgemeine Elektricitäts Gesellschaft AG) business area telecommunications technology was relocated from Berlin to Backnang. In 1955, AEG's microwave radio relay division was relocated from Ulm to Backnang, and Telefunken GmbH was founded. On March 1, 1967, the AEG Telefunken AG was founded with the aerospace specialty and the focus on development, sales, assembly and testing. In 1971, TESAT was involved in their first space project with the Intelsat IV. In 1982, the company was transformed into a GmbH, AEG Telefunken Nachrichtentechnik GmbH. AEG-Telefunken continued to hold the majority with 51% of the shareholder shares, 49% went to a consortium of Robert Bosch GmbH, Mannesmann and Allianz. In 1983, as part of the AEG-Telefunken settlement application, the group's share was withdrawn by the three co-shareholders and divided in the same proportion as the previous shareholder base. The company now operated under the name ANT Nachrichtentechnik GmbH. In 1989, the company became the main Contractor for Deutsche Telekom Kopernikus Satellites. In 1995, ANT Nachrichtentechnik GmbH was transferred to Bosch Telecom GmbH. In 2000, the Bosch space product division was transferred to an independent company, Bosch SatCom GmbH. 2001 was the founding year of Tesat-Spacecom GmbH & Co.KG. In November 2001, Bosch SatCom GmbH was renamed Tesat-Spacecom GmbH & Co.KG and was acquired by EADS Astrium GmbH in December 2001. TESAT was expanded to produce intelligence payloads for satellites and remained as an independent company. In 2006 TESAT was a major Supplier for first Bundeswehr Satellite SAR-Lupe. In 2007 – First flight of TESAT's laser communication terminal (LCT) on the Near Field Infrared Experiment (NFIRE) (First ISL with TerraSAR-X in 2008). In 2013, TESAT manufactured its 10,000th EPC. In 2018, the company celebrated more than 10,000 established Laser links in space. In February 2022, TESAT announced the intention to establish a manufacturing facility in the United States. In April 2026, the company's SCOT80 optical communications terminal was launched aboard the GPS satellite GPS III-10 Hedy Lamarr for the first laser communications test from a GPS satellite at medium Earth orbit.

Products

TESAT's product portfolio ranges from individual components to payloads and complete systems. These are supplied by TESAT to satellite manufacturers worldwide. Among the equipment and systems manufactured for satellite telecommunications are high-power amplifiers such as traveling wave tube amplifiers (TWTA) and their power supplies electronic power conditioner (EPC). TESAT's other product segments include channel amplifiers, filters, multiplexers, modulators, transmitters and TTC transponders.

Worked examples

Example 1 — a first encounter with Tesat-Spacecom

Start with the simplest possible case. Write down what Tesat-Spacecom claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Tesat-Spacecom before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Tesat-Spacecom ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Tesat-Spacecom

In research: Tesat-Spacecom appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Tesat-Spacecom in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Tesat-Spacecom is common in secondary-school and first-year university syllabi. It links to neighbouring topics Aerospace companies of Europe, Airbus Defence and Space, Companies based in Baden-Württemberg, so understanding it makes those chapters shorter.
In everyday life: Look for Tesat-Spacecom outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
