MDA SPACE ACHIEVES AN INDUSTRY FIRST IN SATELLITE DIGITAL BE

July 9, 2025 (Montréal, QC)—MDA Space (TSX: MDA), a trusted mission partner to the rapidly expanding global space industry, announced that it has digitally formed and steered multiple beams with its Ka-band direct radiating array (DRA) using direct sampling, a first in the industry.

Digitally formed beams, multiple simultaneous beams, and electronically steered beams are among the key features of the MDA AURORA™ Ka-band DRA. Their successful validation marks a significant breakthrough in satellite communication systems that support broadband connectivity and 5G networks. It also marks a key milestone in the development of the digital payload technology for the MDA AURORA™ software-defined product line for next-generation satellite constellations.

Beam forming and steering with Ka-band DRAs has typically relied on intermediate frequency conversion whereas MDA Space’s use of direct sampling results in a more efficient and effective approach, allowing customers to save on satellite costs, mass and power consumption. MDA AURORA™ enables the DRA to deliver signals where they are needed and when they are needed, while maximizing the use of the satellite resources.

In addition, MDA AURORA™ is highly scalable, capable of handling hundreds of array elements and providing multiple simultaneous high-capacity spot beams that can be electronically steered, offering a new level of flexibility and performance. This capability is particularly valuable for satellite operators seeking to support 5G networks and the growing demand for data-intensive services, where high-speed, low-latency connectivity is essential.

“With MDA AURORA™, we’re providing a highly flexible and adaptable solution that can be tailored to meet each customer’s specific requirements,” said Luigi Pozzebon, Vice-President of Satellite Systems at MDA Space. “The successful demonstration of our Ka-band DRA technology is a critical step towards delivering those advanced capabilities that will help customers compete in the rapidly evolving satellite communications market.”

Customers can now observe functioning MDA AURORA™ technology in a specially designed demonstration lab at the company’s manufacturing facility in Montréal. This includes the formation and steering of beams through thermal imaging, as the heat the beams generate on the test chamber surface is captured. The lab features a DRA prototype that will ultimately be connected to an onboard processor (OBP) prototype to demonstrate the full communication chain between a gateway ground station and a user terminal, providing a comprehensive view of the system’s end-to-end capabilities.
