​Data Transmission

MDA is a leading provider of data transmission payloads, terminals, and subsystems, with a specialization in Ka-band intersatellite links that support LEO-to-LEO satellite communications, and data relay from LEO-to-GEO satellites.

The company’s heritage in space data transmission includes the NASA TDRSS program in the 1980s, the Iridium 1 and 2 programs of the 1990s, and today’s European Data Relay System.

MDA LEO terminals for scientific or remote sensing missions provide real time data transfer, or real time tasking of the satellite within the view of the Data Relay Satellite to complement standard Line of Site downlinks to regional ground stations.
