This document summarizes technology needs and gaps for satellite communications, tactical communications, and navigation systems. It identifies needs such as improved antennas with better gain-to-temperature ratios and reduced side lobes, more efficient amplifiers, and jam-resistant modems. It also outlines gaps including alternatives to space-based satellites, RF interference mitigation, and dynamic bandwidth interfaces. Additionally, it describes several Small Business Innovation Research projects aimed at addressing these needs, such as a cryogenic analog RF module to increase receive rates and a bandwidth analysis toolkit to model bandwidth demand. It provides points of contact for science and technology issues.
