History

::figure[src="https://upload.wikimedia.org/wikipedia/commons/4/4e/Tesat_home-klein.jpg" caption="TESAT in Backang" alt="Image of a company buildung in Backnang"] ::

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 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In 1983, as part of the AEG-Telefunken settlement application, the group's share was withdrawn by the three co-shareholders and divided in the same proportion as the previous shareholder base.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 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 February 2022 TESAT announced to establish a manufacturing facility in the United States.
