An end-to-end command and control concept for NASA data systems

Abstract

Spacecraft command and control are currently taking on the characteristics of general computer-to-computer interprocess communication. The evolution of these systems during the 1980s will give NASA a true general-purpose end-to-end data request capability for the first time. This concept is presented in outline, with consideration of many of the detailed analyses and subsystem tradeoffs being performed as part of the NEEDS (NASA End-to-End Data System) program.
