X-ray Pulsar Navigation for Crewed Exploration of Cis-Lunar Space and Beyond

Active Technology Project

Project Introduction

This project will establish a hardware-in-the-loop testing capability for X-ray Pulsar Navigation (XNAV) in the context of the Johnson Space Center (JSC) Orion Optical Navigation (OON) testbed, and to identity a practical XNAV sensor package targeting cis-lunar operations for Orion EM2/3 and lunar habitat modules.  This effort will leverage software developments from the Station Explorer for Navigation and Timing Technology (SEXTANT) and hardware concepts from the Neutron-star Interior Composition Explorer (NICER) mission.
