 The Transformational Satellite Communications System (TSAT) aimed to provide the Department of Defense (DoD) with high data rate Military Satellite Communications (MILSATCOM) and
Internet-like services as defined in the Transformational Communications Architecture (TCA).TSAT would have supported global net-centric operations.As the
spaceborne element of the Global Information Grid (GIG), TSAT would extend the GIG to users without terrestrial connections providing improved connectivity and data
transfer capability, vastly improving satellite communications for the warfighter.
