TT&C Systems

SED’s dependable and flexible TT&C systems play a vital role in the management of precious space resources.

Controlling and monitoring spacecraft in GEO, MEO or LEO orbits, our systems are being used in a variety of applications including satellite communications and remote sensing. Our deep space antenna systems even keep track of space probes at the outer reaches of our solar system.

Our turnkey approach includes analyses of requirements, site surveys and selection, system development and tailoring, site preparation and civil works coordination, installation and commissioning, anywhere in the world. The result is a trouble-free delivery of a fully compliant system, tailored to meet specific customer needs. We then provide complete training as well as system, operations and maintenance manuals, and long- term maintenance support.

Customers include Space Systems/Loral, Inmarsat, Teleglobe Canada, ChinaSat, Mabuhay Philippines Satellite Corporation and the Canadian and European Space Agencies.
