About

Peter Steigenberger’s research has fundamentally shaped how the Global Navigation Satellite System (GNSS) community models satellite and receiver antennas. His key contributions center on developing absolute phase-center correction models, which are critical for achieving millimeter-level precision in geodetic applications. Steigenberger led the creation of the igs08.atx model, adopted by the International GNSS Service (IGS) in 2011—a landmark achievement that unified receiver and satellite antenna calibrations for GPS and GLONASS. His most-cited work, “Generation of a consistent absolute phase-center correction model for GPS receiver and satellite antennas” (2007), has garnered over 470 citations, reflecting its foundational role in modern GNSS data processing. He further refined these models for GLONASS and extended GPS antenna patterns to nadir angles beyond 14°, enabling more accurate tracking of satellite signals at low elevations. By integrating robot calibrations for over 200 terrestrial antennas with global tracking data, Steigenberger’s research eliminated systematic errors in positioning, benefiting fields from geodesy to climate monitoring. His work remains a cornerstone of precise GNSS analysis, ensuring consistency across the global IGS network.
