About

Paul Rebischung is a leading figure in geodetic science, specializing in the realization and maintenance of terrestrial reference frames through Global Navigation Satellite Systems (GNSS). His primary research focuses on the precise modeling of GNSS satellite orbits, clock corrections, and antenna phase center variations—critical components for achieving millimeter-level accuracy in Earth observation. Rebischung’s most impactful contribution is his pivotal role in developing IGS14, the International GNSS Service’s reference frame based on ITRF2014, along with the corresponding antenna calibration file igs14.atx. This work, published in 2016 and cited 88 times, provided the geodetic community with a unified, highly accurate framework essential for applications ranging from tectonic plate monitoring to sea-level rise studies. By harmonizing satellite and ground antenna calibrations, his efforts directly improved the consistency and reliability of global positioning products. Rebischung’s achievements underscore his influence in advancing the infrastructure that underpins modern geodesy, making him a key contributor to the precision and stability of Earth reference systems used worldwide.
