"In the Jan-Mar 2005 edition of 'CHIPS', multiple aspects of the Department of Defense (DoD) planned Transformational Communications Architecture (TCA) were explored. This follow-on article focuses on the TCA space segment, which is a composite of space-based assets of the National Aeronautics and Space Administration (NASA), DoD and the Intelligence Community (IC). These combined assets will interoperate and they will be supported by the other three TCA segments, which are primarily earth-bound: the terrestrial infrastructure segment, the terminal segment and the network and management segment. The space segment will extend the Global Information Grid (GIG) to users without fiber connections, providing improved connectivity and data transfer capability resulting in a revolutionary change in satellite communications for the warfighter."
