Professor of Geodesy and Navigation in the School of Civil and Environmental Engineering
Chris Rizos is an Emeritus Professor in the School of Civil and Environmental Engineering and a co-director of the Satellite Navigation and Positioning (SNAP) Lab at UNSW.
Professor Rizos’ early fascination with old maps and Australia’s exploring pioneers sparked his own exploration of what we know today as the global navigation satellite technologies of the future. His research in Global Navigation Satellite Systems (GNSS), and their applications extends across the whole spectrum of uses from Navigation to Geodesy. With over 20 years of service to some of the most prominent international geodetic organisations, he has had the opportunity to be part of the evolution of a field that has considerable global impact.
As a big picture thinker he has watched Geodesy rapidly evolve with its tools and datasets helping geoscientists monitor global change (including natural and climate change), changes in the environment (to ice sheets and atmosphere) and geohazards (volcanos and earthquakes), and surveyors and engineers applying these technologies from small-scale building works to international mapping projects. Through his research, Professor Rizos’ aims to “spatially enable” all aspects of life, through the further development of technologies and systems that provide continuous, seamless, high accuracy positioning of objects, people and every feature on the surface of the Earth.
