| Abstract: | Advanced deep-space communication & navigation architectures based mainly on a recent NASA/SCAWG report are reviewed.Some of the key features are discussed,and a novel Extremely Long Baseline Interferometry(ELBI) approach that puts communication,relay and tracking satellites in the Earth-Moon L3/L4/L5 halo orbits is proposed to enhance the overall system capability and performance. |
