Preliminary concept for lunar exploration tracking and data acquisition and data processing systems

The NASA Office of Exploration is evaluating potential scenarios for an ambitious and complex mission to the moon. This paper sumarizes the initial system engineering analyses being performed to identify the communications, data processing, and navigational support required by these case studies. A feasible option for providing tracking and data acquisition using technology available in the 1990s is described.
