PARIS โ€” Astrium GmbH of Germany is purchasing the space division of German opto-electronics group Jenoptik, Jena-Optronik GmbH, in a cash transaction following a competitive sales process in which Astrium outbid โ€œseveral international aerospace companies,โ€ Jenoptik and Astrium announced Oct. 4.

Financial details were not disclosed, but Jenoptik said the sale will enable it to reduce its net debt, which stood at 144 million euros ($196 million) on June 30, to less than 100 million euros after taking account of an earlier sale, for less than 10 million euros, of a minority stake in a Finnish company.

Jena, Germany-based Jena-Optronik reported about 30 million euros in revenue for 2009 and has 131 employees, all of whom will be kept on by Astrium, which will operate Jena-Optronik as a stand-alone business, much as it does with Tesat Spacecom of Germany and Surrey Satellite Technology Ltd. of Britain.

The transaction is subject to approval by European antitrust authorities.

Jena-Optronik builds satellite attitude-control systems and also provides the laser guidance system used for Europeโ€™s Automated Transfer Vehicle, an unmanned freighter that supplies the international space station. Astrium GmbH is prime contractor for the vehicle.

โ€œThe acquisition of Jena-Optronik will complement Astriumโ€™s optical expertise in Germany and enhance its reputation in the development and production of sophisticated Earth observation satellites,โ€ Astrium said in a statement announcing the sale.

Evert Dudok, chief executive of Astrium Satellites, said the German government โ€œinvests considerably in observation satellitesโ€ and that the acquisition will enhance Astriumโ€™s product offer in the sector.
