Radionavigation

Speaker:

• Dr. Greg Holt - GN&C Autonomous Flight Systems Branch, NASA Johnson Space Center

Speaker Bio:
Dr. Greg Holt is the Navigation Technical Discipline lead and System Manager for the Orion Multi-Purpose Crew Vehicle at NASA Johnson Space Center, having earned a Ph.D. from the University of Texas at Austin and with over 15 years of NASA service.  He has enjoyed many opportunities to be active in technical leadership and is a veteran Mission Control navigator of 8 Space Shuttle missions, the Orion Exploration Flight Test 1, and the Artemis I lunar mission.

Abstract:
Explore the principles and evolution of RadioNavigation, a cornerstone of modern aerospace engineering. We’ll trace the historical progression from early celestial navigation to advanced systems like the Global Positioning System (GPS), Global Navigation Satellite Systems (GNSS), NASA’s Deep Space Network (DSN), and emerging lunar relay satellite architectures for Artemis missions.  Through technical insights, practical examples, and discussions of triangulation, signal processing, and deep-space communication challenges, this talk will illuminate the critical role of radio navigation in enabling precise positioning for terrestrial and extraterrestrial exploration.
