Montreal, QC - MDA, a Maxar Technologies company (NYSE: MAXR) (TSX: MAXR), today announced that it will design and manufacture advanced space-based L-band navigation antennas as part of a hosted payload on the MEASAT-3d satellite, which is currently being built by Airbus. The MDA-built navigation antennas will be integrated on a hosted payload for South Korean KTSAT that will support the Korea Augmentation Satellite System (KASS).

Scheduled for launch in 2021, the KASS navigation payload will deliver L-band regional civil navigation services over South Korea to enhance aviation safety and airplane navigation capability through improved accuracy, reliability and availability of GPS positioning signals.

MDA and its parent company Maxar have successfully hosted more than 10 payloads on the company’s highly flexible 1300-class satellite platform since 2001, covering a wide variety of essential customer missions. In 2012, the company delivered a powerful multi-mission satellite for SES, which included an L-band payload for the European Geostationary Navigation Overlay Service (EGNOS).

“We appreciate the confidence that Airbus has in MDA’s innovative satellite technologies, having worked on over 30 programs,” said Mike Greenley, group president of MDA. “We look forward to continuing our close, collaborative relationship with Airbus on this contract.”
