Ziyang Qu

About

Ziyang Qu is a leading researcher in the field of satellite geodesy, with a primary focus on Global Navigation Satellite System (GNSS) technology and high-precision reference frames. His key research areas include antenna phase center calibration, terrestrial reference frame realization, and the precise positioning of BeiDou (BDS) satellites. Qu’s most notable contribution addresses a critical challenge in geodesy: the high correlation between terrestrial scale and satellite phase center offsets (PCOs), which has historically prevented reliable scale estimation using GNSS. In his highly cited 2021 work, he provided essential phase center corrections for BDS IGSO and MEO satellites within the IGb14 and IGSR3 frames, enabling more accurate satellite orbit determination and terrestrial reference frame alignment. This work has garnered 14 citations and is considered foundational for users of multi-GNSS constellations. By resolving these calibration issues, Qu has directly improved the consistency of global geodetic products, supporting applications from sea-level monitoring to tectonic plate motion studies. His research continues to shape the next generation of precise positioning infrastructure.
