About

Xuanzuo Liu is a specialist in high-precision Global Navigation Satellite System (GNSS) geodesy, with a primary focus on antenna phase center correction (PCC) modeling and calibration. His major contributions lie in advancing the accuracy and reliability of GNSS positioning by addressing critical inconsistencies in PCC models. In his 2022 work, Liu introduced a novel method to evaluate the consistency of PCC models released by different institutes, revealing that numerical differences for the same antenna type can reach several millimeters—far exceeding nominal calibration accuracy. This finding has significant implications for precise geodetic applications, such as reference frame maintenance and deformation monitoring. His 2022 study on the iGMAS BDS/GNSS absolute antenna phase center field calibration further demonstrates his expertise, providing preliminary results that enhance the practical calibration of multi-GNSS antennas. With over 20 citations across his key papers, Liu’s work is gaining recognition for its impact on improving GNSS measurement integrity. His research is particularly valuable for students and researchers in geodesy and satellite navigation, offering rigorous methodologies to address real-world calibration challenges.
