About

Kar-Ming Cheung is a leading expert in deep space navigation and interplanetary communication networks, with a career focused on enabling robust location determination and data relay for Mars and cis-lunar exploration. His major contributions center on developing advanced ranging and Doppler techniques for multiple orbiting spacecraft at Mars, a critical capability for supporting future human and robotic activities on the Martian surface and in orbit. Cheung’s work on the evolution of the Mars Relay Network (MRN) outlines a visionary end-to-end information system for the 2030-2040 human era, addressing the challenges of scaling current infrastructure to meet the demands of sustained Mars missions. He has also pioneered carrier-phase aided pseudo-noise range estimation at RF frequencies, a technique essential for proximity links and spacecraft-to-spacecraft scenarios in cis-lunar space—areas not covered by existing CCSDS standards. With key papers garnering up to 8 citations, Cheung’s research directly shapes the trajectory of NASA’s deep space communication architecture, ensuring that future missions to the Moon, Mars, and beyond have the precise navigation and robust data transmission needed for success.
