TESAT partners with MDA for Telesat Lightspeed

(22 March 2021 - TESAT) TESAT has announced its collaboration with MDA for the upcoming Low Earth Orbit (LEO) satellite broadband network Telesat Lightspeed.

MDA, a Canadian space manufacturer, has been selected to provide one of the critical technology subsystems for this innovative constellation.

TESAT has partnered with MDA as part of the development of the Direct Radiating Array (DRA), a revolutionary phased array that will herald the future of satellite communications.

MDA will deliver over 1000 units for which TESAT, as a collaboration partner, will provide essential power components. These RF modules are based on TESAT’s longtime heritage and knowhow in the development and production of space equipment, paired with its capability and experience in the high reliable and high volume space module production.
