The drivers for future interplanetary communication and navigation

We review future interplanetary missions with the goal of identifying the major drivers for the communication and navigation systems. For a set of 13 characteristic mission scenarios we analyze the communication and navigation architecture and identify the hardware requirements and limiting elements on both, space segment and ground segment. Trends for the design of the communication and navigation systems are identified and analyzed. Special attention is paid to the introduction of advanced concepts such as optical communication and autonomous navigation. The identified design drivers of the communication and navigation systems may serve as a guideline for future technology development activities.
