About

Renyu Zhou is a leading researcher in GNSS geodesy, specializing in the precise calibration and modeling of antenna phase center corrections (PCC)—a critical factor for millimeter-level positioning accuracy. His major contributions center on developing and validating absolute field calibration methods for multi-GNSS receiver antennas, particularly for GPS and BDS-3 signals. Zhou’s work revealed that PCC models from different institutes can differ by several millimeters for the same antenna type, far exceeding nominal calibration accuracy, prompting a new consistency evaluation method. Leveraging a six-axis robot at Wuhan University, he conducted multi-session calibration experiments that significantly improved the reliability of antenna models. His most cited paper (14 citations) introduces a novel approach to assess PCC model consistency, while subsequent studies (6 and 5 citations) present pioneering field calibration results for the iGMAS network and BDS-3 signals. Zhou’s research directly supports high-precision applications in surveying, navigation, and geohazard monitoring, establishing him as a key figure in advancing GNSS antenna calibration science.
