Deep Space X-ray Navigation and Communication (SEXTANT)/NICER
Develop capabilities that will enable sustained human presence throughout the solar system by using Pulsars for autonomous navigation.
High bandwidth communications and advanced navigation capabilities will enable future deep space exploration of the solar system and pinpoint navigation in near-Earth space. The X-ray navigation and communications project element will focus on the development of the X-ray based technologies capable of providing accurate navigation and high bandwidth communications beyond the inner solar system. Technology test beds including those that utilize the ISS will be considered.
