Additional Information

In a contract awarded by the German Federal Ministry of Economics and Technology, the German Aerospace Center is examining the feasibility of a national satellite communications mission based on the preliminary studies (Phase 0) conducted by an industrial team lead-managed by OHB-System. This will form the basis for a national project (Heinrich Hertz communications satellite (H2Sat)).

Named for the German physicist Heinrich Hertz, it is Germany’s first national satellite communications mission since the DFS Kopernikus program involving a satellite engineered and built in Germany. Heinrich Hertz thus marks a further step in Germany’s return to full system capabilities in telecommunications satellites in accordance with the German space strategy adopted in 2010. The Heinrich Hertz mission pursues two goals:

Civil:In-orbit verification of new technologies. For this purpose, roughly one dozen new technologies for satellite communications will be tested on board the satellite and a number of scientific/technical experiments performed.

Military: Communications for the German federal armed forces. A dedicated payload will secure the continued operational capability of the German federal armed forces.
