About
Grzegorz Krzan is a geodesist and GNSS researcher whose work sits at the intersection of satellite navigation, antenna calibration, and geodetic reference systems. Based at the University of Warmia and Mazury in Olsztyn, Poland, Krzan has made significant contributions to the precise calibration of GNSS receiver antennas — a critical but often overlooked factor in high-accuracy positioning. His most cited work (19 citations) rigorously compares robot and chamber-based antenna phase center correction methods for modern multi-constellation GNSS systems, including GPS, GLONASS, Galileo, and BeiDou. Notably, he played a key role in developing a field calibration facility through a European Space Agency project in collaboration with Astri Polska, advancing Europe's capacity for independent multi-frequency antenna calibration. His research further examines how antenna and radome changes introduce systematic offsets in long-term position time series within the EUREF Permanent Network, with important implications for geodetic infrastructure reliability. More recently, Krzan has explored how individual antenna phase center models influence tropospheric delay estimates, connecting antenna metrology directly to atmospheric science. His body of work underscores the foundational importance of antenna modeling in modern GNSS geodesy.
