About

Antonio Tupek is a researcher specializing in high-precision Global Navigation Satellite Systems (GNSS) positioning, with a particular focus on the critical role of receiver antenna characteristics. His work addresses one of the fundamental challenges in carrier-phase-based GNSS: the accurate determination and calibration of antenna phase center variations, which directly impact positioning quality. Tupek has made significant contributions through the development and validation of an absolute field calibration system for GNSS receiver antennas, as demonstrated in his most-cited paper from 2023, which has garnered 8 citations. This work establishes a robust methodology for characterizing antenna electrical signal reception characteristics essential for millimeter-level positioning accuracy. His subsequent 2024 paper provides experimental validation of this calibration system, further solidifying the practical applicability of his approach. By systematically addressing the error source of antenna phase center variations, Tupek’s research supports advancements in geodesy, surveying, autonomous navigation, and other fields demanding precise GNSS measurements. His contributions are particularly valuable for researchers and engineers working to improve the reliability and accuracy of modern positioning systems.
