Montreal, QC - MDA, a Maxar Technologies company (formerly MacDonald, Dettwiler and Associates Ltd.) (NYSE: MAXR; TSX: MAXR), reinforced its position as the leading provider of satellite antennas with over five decades of successful deployments in demanding environments, by signing two multi-million dollar contracts with Airbus comprised of:

• Antennas and deployable reflectors to be integrated into Turksat 5A and 5B telecommunications satellites. These satellites will significantly expand the existing Internet and tele-communication services and provide users in Turkey, Europe, Africa, Middle East North Africa and South-Africa regions with better access to these services.
• Antenna subsystems to be integrated into a second satellite of the Inmarsat-6 mobile communications program. MDA announced the first subsystem in November 2016.

Mike Greenley, group president of MDA said, “Combining leading edge technical capability with timely execution and cost-effective delivery, MDA’s communication solutions provide a unique value proposition to customers worldwide, and underscore why satellite prime contractors return to MDA repeatedly. We are honoured that Airbus has once again trusted us, and we will meet their critical and complex challenges with confidence.”

Airbus also recently recognized MDA in November 2017 as a key supplier for over three decades. This long term relationship has facilitated significant export of leading-edge Canadian technology to enhance multiple Airbus space missions.

MDA’s strong heritage in satellite subsystems positions us as a global leader and the world’s largest independent supplier in the design, fabrication, and testing of innovative antenna products for commercial and civil space markets. A recognized pioneer in Ka-band communications, MDA provides antenna and electronic systems supporting all bands, including recent work in Q/V bands.
