MDA advances European telecommunications capability with proven space systems
Montreal, QC- MDA, a Maxar Technologies company (NYSE: MAXR) (TSX: MAXR), today announced that it has signed two contracts with a total value of more than CA$15 million withOHB System AG(OHB) andTesat-Spacecom GmbH & Co. KG(Tesat) for multiple advanced communication subsystems that will be used on Germany’s Heinrich Hertz communications satellite.

These communication subsystems provide the critical link between the spacecraft payload and the ground segment gateways and service users. In geostationary orbit, they comprise the elements that receive and broadcast telecommunications, internet and digital entertainment to billions of users. Orbiting Earth at more than 35,000 km, it is imperative that communication antennas, reflectors and related structures and mechanisms are at the same time highly advanced and very reliable, to ensure the performance and success of long-term commercial and military missions.

Heinrich Hertz Satellite Mission is a national communications satellite program of the German Space Agency, DLR that will extend German capabilities in satellites and telecommunication payloads. The mission will explore and test a range of new space technologies, including the impact of broadband on achieving higher data speeds for mobile final users. MDA is providing additional communications subsystems as well as control electronics for Heinrich Hertz Satellite under aseparate contract.

MDA satellite payloads, antennas and electronics have enabled fixed, high-throughput and mobile communications systems, space radar missions, exploration, science, navigation, remote sensing downlink, telemetry and command systems and inter-satellite communications. A technical pioneer for more than 50 years, MDA is now the industry’s largest independent supplier, with Industry 4.0 smart factory standards that link automation, data exchange, real-time communications and the Internet of Things to empower better processes, smarter decision-making and the creation of new quality standards for deployed space systems.

“MDA is pleased to extend our long relationship with OHB and Tesat in the advancement of space technology,” said Mike Greenley, Group President of MDA. “I am excited that these world-leading organizations trust MDA communication solutions to play a role in their industrial development. These contracts underscore the inherent value and quality MDA brings to all its antennas, electronics and payloads.”
