data handling and distribution, improvements in navigation accuracy, development of integrated communication systems, and identification of potentially revolutionary technologies.

Before prioritizing the level 3 technologies included in TA05, several technologies were renamed, deleted, or moved. The changes are explained below and illustrated in Table H.1. The complete, revised technology area breakdown structure (TABS) for all 14 Tas is shown in Appendix B.

5.6.7.    Reconfigurable Large Apertures

Rename: 5.6.7. Reconfigurable Large Apertures Using Nanosat Constellations

NOTE: Technologies 5.4.1, Timekeeping, and 5.4.2, Time Distribution, have been merged and renamed: 5.4.1 Timekeeping and Time Distribution because the technologies are very similar and it would be most effective to develop them together. Technology 5.6.7, Reconfigurable Large Apertures, has been renamed 5.6.7 Reconfigurable Large Apertures Using Nanosat Constellations to better indicate the content of this technology as described in the TA05 roadmap.
