JPL DESCANSO - Deep Space Communications and Navigation Center of Excellence



Kar-Ming Cheung

Kar-Ming Cheung received his B.S. EE from the University of Michigan, Ann Arbor in 1984; and his M.S. and Ph.D. from California Institute of Technology (Pasadena) in 1985 and 1987, respectively.

In 1987, he joined the Communications Systems and Research Section at the Jet Propulsion Laboratory (JPL). In the earlier part of his career at JPL, he worked on the research and development of error-correction coding, data and image compression, synchronization, and system analysis of the NASA's Deep Space Network (DSN) communications system.

In the mid-1990s, when the Galileo spacecraft lost the use of its high-gain antenna, Dr. Cheung implemented a low-complexity data compression software scheme that increased Galileo's data return by a factor of 10. He also led development of the error-correction coding scheme, which was part of the ground-enhancement effort to further increase Galileo's data return. He received the NASA's Exceptional Achievement Medal for his contribution to the Galileo Project.

Dr. Cheung is currently a principal engineer and technical group supervisor of the Communications Systems and Research Section's Telecom Architecture Group. He continues to support the multi-mission telecom link analysis tools development and to lead a multi-center team on architecture and system engineering trade studies to support the Space Communications and Navigation (SCaN) Office of NASA.
