About

Jacek Paziewski is a leading figure in geodesy and satellite positioning, with a primary focus on advancing the precision of Global Navigation Satellite Systems (GNSS). His research centers on improving tropospheric modeling, multi-GNSS data processing, and antenna calibration techniques. Paziewski’s major contributions include demonstrating how individual antenna phase center models and the integration of multiple GNSS constellations (GPS, GLONASS, Galileo, BeiDou) significantly enhance the accuracy of Zenith Total Delay (ZTD) estimates—critical for weather forecasting and climate studies. His work has shown that careful processing strategies can reduce biases in tropospheric time series, directly impacting numerical weather prediction models. With over 1,000 citations across his publications, Paziewski’s studies are widely referenced in the geodetic community. Notably, his 2023 paper on antenna calibration and multi-GNSS observations, though recent, has already garnered attention for its practical implications. He has also contributed to the development of precise point positioning (PPP) techniques and served as an editor for leading journals, solidifying his reputation as a key innovator in high-precision GNSS applications.
