YANG Xuhai was born in Weinan, Shaanxi, China, in 1972. He received the B.S. degree in applied physics from Northeastern University, Shenyang, China, in 1995, and the Ph.D. degree in astrometry and celestial mechanics from the Graduate School of the Chinese Academy of Sciences, Beijing, China, in 2003.

Since 2007, he has served as the Director of the Orbit and Time Transfer Department, National Time Service Center, Chinese Academic of Sciences, Xi’an, China. He has authored over two books, 50 papers, and holds several patents. His research interests include high-precision time transfer, orbit measurements, and orbit determination.
